How Does Power Steering Work?

Understanding the basic principles of a power steering system can help you better identify potential problems. There are two main types of power steering systems: hydraulic and electric.

• Hydraulic Power Steering: This traditional system utilizes a hydraulic pump powered by the engine’s crankshaft. The pump pressurizes power steering fluid, which is then directed to a steering gear unit. As you turn the steering wheel, the fluid pushes on pistons within the steering gear, assisting you in turning the wheels.
• Electric Power Steering (EPS): A more modern system, EPS employs an electric motor to provide steering assistance. Sensors detect your steering wheel movements, and the motor applies the necessary torque to the steering gear, making turning easier.

Both systems rely on various components working in harmony to ensure smooth and responsive steering.

The Most Common Power Steering System Failures

Several issues can lead to malfunctioning power steering. Here’s a breakdown of the most common failures:

1. Low Power Steering Fluid

• Symptoms: The most noticeable symptom of low power steering fluid is a significant increase in steering effort. The steering wheel will feel stiff and require more muscle power to turn, especially at low speeds. You might also hear whining or grinding noises when turning the wheel.
• Causes: Low power steering fluid can be caused by a leak in the system, a faulty pump not generating enough pressure, or even overfilling the system during a fluid change.
• Solutions: Check your power steering fluid level regularly according to your vehicle’s owner’s manual. If the fluid level is low, look for signs of leaks and consult a qualified mechanic for proper diagnosis and repair.
• Prevention: Regularly inspect your power steering system for leaks. Schedule routine maintenance checks with a mechanic to ensure the system is functioning properly and fluid levels are topped up if needed.

2. Faulty Power Steering Pump

• Symptoms: A failing power steering pump can manifest in several ways. Like low fluid, you’ll experience increased steering effort, especially at low speeds and when parking. Whining or grinding noises when turning the wheel are also common signs. In severe cases, the power steering might completely fail, making steering extremely difficult or impossible.
• Causes: Power steering pumps can wear out over time due to normal use and tear. Contaminated fluid due to infrequent changes or leaks can also damage the pump.
• Solutions: Replacing a faulty power steering pump is typically a job for a qualified mechanic. If you suspect a pump issue, avoid driving the car and seek professional help immediately.
• Prevention: Regularly maintain your power steering system by following the manufacturer’s recommended fluid change intervals. This helps prevent wear and tear on the pump and keeps the system functioning optimally.

3. Power Steering Leaks

• Symptoms: Leaks are a common cause of power steering system failures. Signs of a leak include low power steering fluid levels, even after topping up, visible puddles of red fluid under your car near the front wheels, and a whining noise when turning the wheel.
• Causes: Power steering leaks can originate from various components, including worn hoses, loose connections, faulty seals, or even a cracked steering gear unit.
• Solutions: Identifying the source of the leak is crucial. While minor leaks might be addressed with replacing a hose or tightening a connection, more extensive leaks might require professional repair or component replacement. Never ignore a power steering leak, as it can lead to complete system failure.
• Prevention: Regularly inspect your power steering system for signs of leaks and damage. Schedule routine maintenance checks with a mechanic to identify any potential issues early on.

4. Worn Steering Gear

• Symptoms: A worn steering gear can manifest in several ways. You might experience increased steering wheel effort, particularly noticeable at low speeds. The steering wheel might feel loose or unresponsive, and you might hear clunking noises when turning the wheel. In severe cases, the steering wheel might vibrate or exhibit excessive play. This can make driving unsafe and lead to difficulty maintaining control of the vehicle.
• Causes: Steering gears experience wear and tear over time due to friction and constant use. Contaminated power steering fluid due to infrequent changes or leaks can accelerate wear on the gear’s internal components. Additionally, aggressive driving habits or excessive stress on the steering system, such as frequent off-roading, can contribute to premature wear.
• Solutions: Replacing a worn steering gear is typically a complex repair requiring a qualified mechanic. If you suspect a steering gear issue, avoid driving the car and seek professional help immediately.
• Prevention: Regularly maintain your power steering system with proper fluid changes and avoid aggressive driving habits. Schedule routine maintenance checks with a mechanic to identify any potential problems with the steering gear early on.

5. Faulty Power Steering Pressure Sensor

• Symptoms: A malfunctioning power steering pressure sensor can cause a variety of issues. You might experience inconsistent steering effort, with the steering wheel feeling stiff at times and loose at others. The ABS or traction control warning lights might also illuminate on your dashboard.
• Causes: The power steering pressure sensor monitors the system’s hydraulic pressure and relays this information to the vehicle’s computer. A faulty sensor can send inaccurate readings, leading to erratic behavior in the power steering system.
• Solutions: Diagnosing a faulty power steering pressure sensor typically requires specialized tools and expertise. Consult a qualified mechanic for proper diagnosis and replacement of the sensor if needed.
• Prevention: While there’s no specific preventative measure for sensor failure, maintaining a healthy power steering system with clean fluid and proper maintenance practices can minimize the risk of sensor malfunction.

Warning Signs to Not Ignore

A properly functioning power steering system is crucial for safe driving. Here are some warning signs to pay close attention to:

• Difficulty turning the steering wheel, especially at low speeds
• Whining, grinding, or clunking noises when turning the wheel
• Leaks or puddles of red fluid under your car near the front wheels
• A loose or unresponsive steering wheel
• Vibrations in the steering wheel

If you experience any of these symptoms, don’t ignore them. Ignoring power steering problems can lead to complete system failure, making driving dangerous and potentially causing an accident. Schedule an appointment with a qualified mechanic as soon as possible for a proper diagnosis and repair.

Maintaining Your Power Steering System for Optimal Performance

Here are some tips to keep your power steering system functioning smoothly for years to come:

• Regular Maintenance: Follow your vehicle’s manufacturer’s recommendations for power steering fluid changes. This helps remove contaminants and ensures proper lubrication of the system’s components.
• Leak Inspections: Regularly inspect your power steering system for signs of leaks. Look for cracked hoses, loose connections, or puddles of fluid under your car.
• Avoid Aggressive Driving: Aggressive driving habits like hard turns or frequent maneuvering at high speeds can put extra stress on the power steering system. Practice smooth and controlled driving techniques.
• Use Approved Fluids: Always use the power steering fluid recommended by your vehicle’s manufacturer. Using the wrong type of fluid can damage the system’s components.

By following these tips and addressing any issues promptly, you can ensure your power steering system operates optimally, providing a safe and comfortable driving experience. Call us now at 949-583-0811 for your power steering system repair in Mission Viejo, CA.

When undertaking performance tuning for Japanese cars, it’s essential to consider the intended use of the vehicle, budget constraints, and the expertise of qualified professionals to ensure safe and effective upgrades that enhance both power and handling characteristics. Additionally, always adhere to local regulations and laws regarding vehicle modifications and emissions compliance.

How often do Japanese-manufactured cars need oil changes?

When you read the car owner’s manual’s fine print, the factory recommendation for car oil changes is between 3,500 and more than 10,000 miles. However, if you have a mechanic that specializes in Japanese cars, they will ask you about your driving conditions, and then make the frequency determination as to what type of oil and oil filter your car needs.

Most mechanics, using those same factors of driving style, will recommend Japanese car oil changes every six months or every 5,000 miles, depending on which comes first. Is it OK to wait for car oil changes for a car with low mileage? Again, it will depend on your driving style, but in normal driving conditions as opposed to severe driving conditions, car oil changes can be done once a year. 

What is considered severe driving conditions?

Severe driving conditions are described in some car owners’ manuals as: 

• Making frequent short trips under ten miles round-trip, especially in cold weather
• Driving in heavy traffic that requires a lot of stop-and-go traffic
• Driving on dusty, gravel roads
• Driving on highways a lot, especially in the summer

 Is one type of car oil better than others? 

Car engine oil has different thicknesses, for hot and cold temperatures. A car engine needs to be matched up with the right thickness with each car oil change. For a top-quality oil, the one characteristic you want to make sure of is testing standards, like the American Petroleum Institute or a recognized international testing standard. 

If an API (American Petroleum Institute) is mentioned in car engine oil, you can feel comfortable knowing it is a tested product and found to be a good match. The last factor to be concerned with for a Japanese car oil change is that you get a full synthetic oil. 

How much does a car oil change cost for a Japanese car?

Some factors have an impact on car oil changes like the year, make, and model of the car, and the engine size. The engine size will determine the amount of oil needed. And if you choose a synthetic or semi-synthetic oil, the prices can vary a little bit between oil change centers, or if you choose a big box store mechanic service. The average cost today is around $100.00. The cost of crude oil by the barrel can affect the cost of car oil changes too. 

Are Japanese cars expensive to maintain?

Japanese-manufactured cars have a reputation for being durable and reliable. With that being said, they have less downtime, but when they need major repairs, it can be expensive. A Japanese car oil change is typically not any more expensive than other cars. 

What is the lifespan of Japanese cars? 

The average lifespan is around 10 years, but many car owners trade their cars every 3 to 4 years to have a new car warranty. Like any car, the driving conditions, driving style, and maintenance and upkeep routines, like scheduled car oil changes, will have an impact on the lifespan of any car. 

What happens when you don’t get a car oil change in a Japanese car?

When you drive over the recommended mileage for a car oil change, as the engine heats up, it doesn’t function as well and the components wear out faster. Like an American-manufactured car, the internal parts of the engine are metal, and fresh oil is necessary to keep them lubricated to prevent friction. 

 What are signs it is time for a car oil change?

Most oil change centers and garage shops put reminder stickers inside the driver’s side windshield. But you should be familiar with what indicators are telling you it is time for a car oil change: 

• Strange Smells and Sounds

When car oil gets old, it can start to smell and you may hear loud sounds coming from the engine. In these instances, it is time for a car oil change. 

• Oil and Smoke

A translucent trail of smoke coming from the tailpipes in the winter is normal, but if that smoke continues as you drive down the road, you may have an oil leak. Or when you check your oil, if it dark, dirty, or gritty, it is time for a car oil change. 

• Can’t Remember The Last Time

If you aren’t able to remember when you got the last car oil change, you probably need to schedule one now! 

 In Closing

Next to your home, your car is an expensive and important investment. By maintaining a regular car oil change schedule, you’ll get a longer lifespan from your car. If you need a car oil change in Mission Viejo, CA, please reach out to our team today at 949-583-0811.

What is brake fluid and what does it do?

Brake fluid is a hydraulic type of fluid that runs through brake lines, reaching each wheel of a car. When the brake pedal is pressed, the brake fluid lets that force from pushing the pedal be applied to the brake lines, slowing the vehicle down to a complete stop. 

Should brake fluid be replaced, and if so, how often? 

Over time, brake fluid breaks down. Some vehicle manufacturers recommend changing the brake fluid every 24 months. Other vehicle manufacturers recommend changing the brake fluid every 45,000 miles or every 3 years, whichever comes first.

Are there different types of brake fluid?

The braking system on every vehicle is designed to use a specific type of brake fluid. When it is time to add or change brake fluid, it is necessary to use the appropriate type. As mentioned earlier, brake fluid is a hydraulic type of fluid that relies on incompressible fluid to transmit force. 

When brake fluid reaches a certain boiling point, it becomes a gas substance and loses some of its braking power. This is why “riding your brakes” is not recommended. The different types of brake fluid are: 

• DOT3
• DOT4
• DOT5 

• DOT3 and DOT4 brake fluids absorb water and as it heats up to a boiling point, the water decreases. This saves your brake system from rusting.

• DOT5 brake fluid doesn’t absorb water so the boiling point remains reasonably stable. However, because it doesn’t absorb water, if any water gets in the brake system, you can expect to need brake repair or replacement. 

What are the dangers of using the wrong type of brake fluid? 

Using the wrong brake fluid is just as damaging as using the wrong gasoline or oil. The lubrication process is affected and can lead to the brakes overheating. It can even cause your transmission to fail and the worse part of this is that the damage may not be repairable. 

What are the signs of a brake fluid leak? 

Properly working brakes have sufficient brake fluid and tightly connected brake lines. How can you tell if your car is leaking brake fluid? 

• FLUID UNDER THE VEHICLE

If your vehicle has brake fluid leaking, it will be a brownish, light yellow fluid pooling at the rear wheels. 

• WARNING LIGHT ILLUMINATED

When the brake light is illuminated and stays illuminated, you need to have the brake fluid and the entire brake system checked. 

• SOFT, SPONGY BRAKE PEDAL

When you press on the brake pedal and it feels soft or spongy, check for the brake fluid. If the level is okay, take your car in for a brake inspection and repair. 

• BRAKE FLUID LEVEL LOW

If the brake fluid level is low over a period of time, you probably have a brake fluid leak. You can check the brake fluid reservoir yourself or have your mechanic check it for you. 

What should I do if my brake fluid is low? 

If you have checked your own brake fluid level, you probably know where to add more brake fluid. This should be done before you drive the car any further.  If you have your brake fluid checked by a mechanic, they will add more fluid for you. If this is done while you’re getting your oil changed, some stations won’t charge you for the brake fluid. 

How can I tell if my brake fluid needs to be flushed?

In addition to having soft or spongy brakes, or the brake light is illuminated on your dash, there are two more indicators you need to have your car’s brake system flushed: 

• Braking Performance Ineffective

Your vehicle’s brakes should be quick to respond when you press the pedal. If it delays in reacting or appears to have difficulties in slowing or stopping, have your mechanic do a brake flush and inspection. There may be warped rotors, the brake pads are worn, or there may be other issues with your vehicle.   

• Strange Odors and Sounds

If you notice strange odors or sounds when you press the brake pedal, it could be an indication the brake fluid is low.

Why do we have to get emissions testing done?

In 1977, the federal government enacted an amendment to the CAA requiring all cars must undergo I/M inspection and maintenance programs to ensure they weren’t emitting more greenhouse gases and pollutants than each state’s limit. It is said by many that the state of California has some of the strictest guidelines when it comes to emissions testing, but other states with a high concentration of vehicles on the road have strict limits as well, like New York City. 

What are the emissions testing limits in California?

Your vehicle must show during the emissions testing that it has achieved optimum fuel combustion with a ratio of air to fuel of 14.7:1 during the combustion process. It is allowed a variance of +/- 5% to help the catalytic converter operate. 

In certain counties in California that have been declared to have a pollution problem, all vehicles are required to pass emissions testing using the Enhanced Version of the emissions testing. This is where a vehicle is connected to the dynamometer and ‘driven’ on the machine while the emissions testing samples are collected from the tailpipe. The emissions testing applies to vehicles that are 1976 and newer, including gasoline-powered, hybrid vehicles, and alternative-fuel. 

How often does an emissions test need to be completed? 

As in most states, the state of California requires emissions testing on vehicles manufactured in 1976 and newer. What types of vehicles are exempt from emissions testing in California? An exception to this is diesel-powered vehicles manufactured in 1997 and older years have a GVW (Gross Vehicle Weight) of 14,000 pounds and up.

What types of pollutants are tested for during an emissions test? 

During emissions testing, the parts per million are tested for carbon monoxide and hydrocarbons that are being released as the vehicle is ‘driven’ on the dynamometer. What are the consequences of failing an emissions test? If the testing results don’t fall within the permissible criteria, the vehicle fails and cannot be driven until the matter is fixed and rested.

What are the benefits of passing an emissions test? 

Another year of happy motoring!  And you’ll know you’re doing your part in minimizing your carbon footprint by contributing less to the pollution problem that is plaguing this country.

Are emissions tests required in all states? 

Currently, there are thirty-four states that require emissions testing for vehicles with each state having its own requirements and rule. In some states, emissions testing is only required in certain counties, typically determined by population. You should check with the DMV in your state for exact requirements and rules in certain areas.

Five Signs

The following five signs are signs brake pads need replacing: 

• Squeaking or Squealing 

This is usually the first sign that the brake pads need to be replaced, if the squeaking or squealing is persistently, non-stop.  

• Indicator Light 

In newer cars, they are equipped with brake pad sensors that trigger the brake light. If the indicator light is illuminated, this is another indication that the brake pads need replacing.

• Metal Grinding 

If you hear the sound of metal grinding on metal, it is time for new brake pads. 

• Vibrating Pedal

When you press on the brake pedal and it vibrates, this indicates the brake pads have worn down. Usually, the metal grinding follows next.

• Fourth Inch Thick

When you take your car to the mechanic, they will measure the brake pad thickness. If they are thinner than one-fourth of an inch, it is time for replacements. 

How do I check my brake pads?

The best way is to have a professional mechanic inspect your brakes. But you can check them yourself using the following steps after they have cooled down. 

1. Check the brake fluid. If the brake fluid is dark, it is time for a brake system to flush and new fluid. 
2. Check the wheels for a buildup of brake dust. Brake dust is good, that means your brake pads are working. IF there is no brake dust, the brake pads are worn and need to be replaced.
3. Inspect the brake pads through the slots of the wheels. Using a flashlight and if they are ¼” thick, or thicker, they are still good. 
4. Remove the wheels and examine the brake pads if you can’t see them through the wheel slots.  Make sure your car is on level ground and the wheels are scorched. Raise the car six inches up and remove the lug nuts and tires. You should have a clear view of the brake pads. Again, if they are ¼” thick or thicker, they are still good. 

Can I drive with brake pad warning light on?

If the brake light comes on, this is telling you it is time to have the brakes inspected while you still have brake pads left. Yes, you can drive the car for a short time, but too much driving will wear through the pads, to the rotors, and leave you with some expensive damage to repair. 

Can I just replace brake pads and not rotors?

Yes, if the brake rotors aren’t damaged or have worn too thin, changing just the brake pads will be sufficient. This is another time that taking your car to an experienced mechanic is the best solution, they are knowledgeable about the proper thickness of the rotors and pads. 

Should you replace all 4 brake pads at once?

Yes, even if they don’t all look to be worn the same, change all four brake pads at the same time. However, if they aren’t worn out approximately the same, you should have the complete brake system inspected. 

Do front brake pads wear faster than rear?

Yes, this is due to the bulk of the weight riding on the front ends when the brakes are applied. Over time, friction and heat contribute to the wear of brake pads.

Before You Hit The Road …. 

Before you start out on your vacation road trip, make sure your gas tank is full, the oil is at the proper level, and have your brakes checked. What is the average life of brake pads? There are several different compositions and types of brake pads and even more different rotors. The general mileage you can expect from your brake pads is between 30,0000 miles and 70,000 miles, with many of them lasting up to 100,000 miles.

How much does it cost to check the AC in a car?

In California, you pay up to $300 for a professional diagnosis and inspection of your car’s air conditioning system. This includes the following components are checked: 

• Belts
• Connections
• Hoses
• Pressure lines

The technician will check for leaks and add removing all existing refrigerant before adding new refrigerant, which can cost an additional $150 to $250, depending on how many pounds are needed. If any additional car AC repairs are needed, like new belts, connections, or hoses, there will be additional costs.

Why is my car AC blowing cool air but not cold?       

If you have your car air conditioning set at max cool with the fan blowing high, but the air isn’t cold, check the following: 

• Are the condenser or radiator cooling fans running while the AC is on?
• Is there debris, leaves, bugs, or other articles blocking the condenser?
• Check the cabin air filter isn’t clogged.

If all of this is in proper order, you can do your own pressure check if you have the equipment needed or schedule an appointment with your mechanic. This requires specialized car AC repair gauges and tools that check the high side and the low side pressure of the AC system. 

Most car AC repairs are for leaks within the air conditioning system, typically indicated by low pressure reading on the gauge.  Leaks are common around the connections and fittings, compressor hoses, O-rings, pressure switches, and seals. A hose could be crimped or the developed pinholes. 

Does car AC refrigerant run out and keep my car AC from blowing cold air? 

No, the refrigerant gas in your car’s air conditioning system doesn’t get ‘used up’ or ‘wear out’ like the motor oil and gasoline. If the air conditioning system is properly sealed, it shouldn’t ever ‘run out’ or be used up. 

It is common for most drivers to assume this is how the coolant or refrigerant works in their car’s air-conditioning system. But, as we just stated, if the system is properly sealed, the air conditioner can cool for years without any refrigerant being added. 

Yes, if the air-conditioning system in your car is losing the compressed refrigerant, it will keep the system from blowing cold air. The refrigerant gas of “Freon” is turned into a liquid as it goes through the system. It then releases the gas through the evaporator coil and then expands as the gas chills there, drawing heat from the air as it passes over. That chilled air then blows through the air-conditioner vents and keeps you cool.

So, if the system has leaked the refrigerant, your car will be filled with warm to hot air. When this happens, take your car in for professional car AC repairs. It could be an issue with the pressured lines or a leak in a hose. 

Why did my car AC suddenly stop working?

If your car’s AC just quit working all of the sudden, it is probably an electrical problem. It could be a blown fuse, the control module is malfunctioning, or the switches failed. A professional car AC repair shop can diagnose the problem and get your car cooling again. 

How do I know if my car AC compressor is bad?

If you are noticing any of the following, you need to schedule an appointment with your mechanic for car AC repair service before the compressor totally quits: 

• Odd Noises: Odd, strange noises when the air conditioner is turned on are typically coming from the compressor. This component is a vital part of your car’s air conditioning system and if it is making grinding or whining sounds, the internal bearings are going bad. 

• Hot Air: If your car’s AC isn’t blowing cold air through the vents, it is out of refrigerant and that is probably because the compressor has leaked it all out. As soon as the air is feeling warm from the AC, schedule a car AC repair appointment and have it checked. 

• Leaking Fluid: The air-conditioning system in your car should not have any leaking fluid. This is an indicator that the internal bearings of the compressor are not doing their job, probably because they are worn out. 

• Clutch Stuck: Your car’s AC compressor has a clutch as a manual transmission does, and it pulls power from the engine to make the AC work. If that clutch malfunctions or stops working, the compressor quits working too.

Can I just replace my car AC compressor?

Yes, a compressor can be replaced without having to replace the entire air conditioning system, but it is recommended to this be done by a professional car AC repair service center. A car AC system is under pressure, and it can be dangerous if you aren’t equipped with the proper tools and follow the proper procedure. 

Should I replace my car AC condenser?

If the compressor to your car air conditioning system has gone out, a professional car AC repair service center will typically recommend replacing the condenser too. If the condenser is leaking, it should be replaced, but the compressor may not need replacing at that time. 

Is a check engine light always bad?

Not necessarily – the check engine light is a malfunction indicator lamp for the automotive industry. It is a signal from the engine’s computer telling you something is wrong. Sometimes a check engine light diagnostic will find the light came on simply because the gas cap was faulty. You can replace your gas cap as an easy way to see if the check engine light turns off. 

But often, it does mean something is seriously wrong – like the engine misfiring. If replacing the gas cap doesn’t turn the light off, you’ll be left asking yourself, “Why is my check engine light on?”. Well, you’ll need to take your car to your mechanic or the dealership where they can perform a check engine light diagnostic test to answer that question.

What is the most common reason for a check engine light?

After the possibility of a faulty gas cap, here are five other common reasons a professional check engine light diagnostic testing may find your light is on: 

• Dirty or Low Oil 

Oil is needed to lubricate the engine components and reduce friction and wear & tear of those components. This allows them to run smoothly and protects them from damage. That oil also minimizes the heat that generates in an engine while driving. 

Low oil pressure or dirty oil will cause the check engine light to illuminate because the oil isn’t getting where it needs to be. Have your oil changed immediately and see if that fixes the problem. If not, a check engine light diagnostic may find another one of these issues.

• Oxygen Sensor Failure

The oxygen sensor is in the exhaust system and measures the amount of oxygen in the exhaust gasses coming from the engine. This data goes to the onboard computer and determines if the air-to-fuel ratio is correct. If not, the oxygen sensor alerts the computer, and the check engine light comes on. 

An oxygen sensor can fail when the contaminants like phosphorus and silicates get in the exhaust. This can happen when poor-quality fuel is used. If your car’s gas mileage is getting worse, the check engine light will come as well.  A professional check engine light diagnostic test will tell a mechanic precisely the problem and it can usually be remedied. 

• Catalytic Converter Failure

The catalytic converter cleans the exhaust emissions by converting the harmful compounds into safe gasses. When the converter becomes clogged by coolant and engine oil, it will send a signal to the computer and the check engine light illuminates. 

The CEL will also come on when the catalytic converter overheats because of unburned gas or a faulty oxygen sensor. If you’re having trouble starting your car or accelerating, it could be that the catalytic converter is having issues. 

• Spark Plugs

Spark plugs create an electrical spark that ignites the air and fuel mixture in the engine, resulting in the combustion that is needed for a car to start. When carbon, fuel, or oil deposits form on the spark plugs, the spark plugs become corroded. This causes them to misfire, which can lead to difficulties starting your car. 

When your engine is hesitating at take-off, misfiring, or has a rattling or vibrating noise while idling, the CEL is likely coming on too. You should schedule a check engine light diagnostic test with your mechanic at this point. Changing the spark plugs will usually fix the problem. 

• Air Flow Sensor Failed

The mass airflow sensor is part of the electronic fuel injection system. It calculates the amount of air getting to the engine, but if it is contaminated or damaged, it can’t measure the airflow correctly. Then the engine gets a wrong mixture of oxygen, and the check engine light comes on. 

A professional check engine light diagnostic by your mechanic can determine this problem and make the appropriate adjustments or repairs needed. 

Will a check engine light come on for transmission?

Yes – if your car is having transmission problems, the check engine light may come on. However, that problem is not as obvious as other issues and a professional check engine light diagnostic is needed to determine the exact problem. 

Will a check engine light come on for low oil?

Absolutely, and this could be considered the number one problem after a check engine light diagnostic is done by mechanics. Keeping the oil checked on a regular basis and maintaining a schedule for changing the oil is a must for a car to keep running correctly. 

Can I drive with the check engine light on?

Yes, for a short time. Once the CEL is illuminated, you need to schedule an appointment with your mechanic for a professional check engine light diagnostic test. It may be something as simple as a loose or faulty gas cap, but it can also be something more serious. The longer you drive with the CEL on, the higher the chance you may break down.

Every driver should know what to do when the check engine light comes on, and that is contact your mechanic immediately for an appointment. If the car is running badly and the CEL is on, pull over to a safe place and call a tow truck. Until a check engine light diagnostic is done, you should quit driving the car. 

In general, it takes a person that has been trained and who has the proper experience to know how an electrical system works in a car. That person may not be your usual mechanic because just as doctors have specialties, so do mechanics and technicians. So when you need car electrical system repairs, your usual mechanic may hand the job over to one of their counterparts. 

What is the importance of the automotive electrical system?

The first important thing to know about a car electrical system is that it provides the electrical current your car needs to start. And once your car starts, it powers other important components within your car. From the ignition that starts your car and the fuel system that keeps your car going, without the electrical system powering them, nothing would happen.

And it goes beyond starting and powering your car. The battery depends on the electrical system and the electrical system depends on the battery. Often, when a battery goes bad or is installed wrong, it can create a need for car electrical system repair services. In addition, the automotive electrical lighting system, including the turn signals and emergency flashers and even any alarms you have installed, all depend on the electrical system to be in working order.

What are the major components of the electrical system in a car?

There are many different components and parts to an electrical system of a car, but the three main ones are: 

• The  battery
• The alternator
• The starter 

All three of these component must be synchronized to  work together in order for your car to start and to keep running. If one of the other goes out, the other two can’t do their job. Additionally, each of them can cause other problems that require professional car electrical system repair service. 

How do I check the electrical system in my car?

Dealing with a car that won’t start is frustrating, and if it isn’t the battery, the situation can be really frustrating. This is not only possible but common in newer cars. The electrical system in cars today is much more complicated and extensive than in cars made 20 years ago. 

Technological advancements have been great in many ways, but they have also created a car electrical system repair nightmare too. Diagnosing car  electrical issues is a challenge, but a few things you should be aware of are: 

• Engine Not Starting Correctly

Electrical power is needed for your car to start; this comes from the battery. If your car isn’t starting, it may be the battery or it could a host of other things.  If there is clicking while you’re trying to start it, it may be the alternator or starter. 

• Problem with the Battery 

A battery that is dead or discharged is definitely needing car electrical system repair, which is simply replacing the battery. Or it could be corroded battery cables, incorrect battery connection, etc. 

• Malfunctioning Lights

The lights on your car are critical for safety. The brake lights, headlights, turn signals and more.  They all play a part in keeping you and others around you safe while on the road. 

• Blown Fuses

The fuse prevents your car’s electrical system from short-circuiting and going over voltage. If the fuses keep blowing for indiscernible reasons, you need to schedule car electrical system repair service as soon as possible. 

• Burning Plastic Odor

If your car is exhibiting any of the electrical symptoms we’ve mentioned and you’re smelling burning plastic, don’t wait to schedule a car electrical system repair. Take the car immediately to a mechanic. There could be a problem within the automotive relay that needs to be replaced.

What is an automotive relay?

Your car will have several automotive relays. Every vehicle, regardless the make or model, has them; they are what enables a small current flow circuit to have control and operate the higher current circuit. 

How do you wire an automotive relay?

There should be an automotive relay for every circuit that is added to a modern car. Cars today come from the factory with light gauged wiring that is not able to handle additional electrical loads like sound systems. A relay will provide power to a new circuit without drawing much from the current of the original wiring. 

Step 1: Connect relay terminal 87 to the car body or the battery negative terminal with 18-gauge primary wire and solder-less female spade connector and a solder-less ring terminal.

Step 2: Connect relay terminal 85 to a car’s circuit breaker and connect the circuit breaker to another terminal, and then to the battery’s positive terminal with a primary wire that can handle the device you are adding to the current load.

Step 3: Connect relay terminal 86 to the new device you’re adding that needs power with the same gauge wire you used for terminal 85.

With other hybrid car repairs, let’s consider the team that is meant to work together powering and moving a hybrid car: 

• The combustion engine
• The electric drive motor
• The transmission

All three of these components need to work together to provide a hybrid car power. When one of them fails, the other two quit. It is critical to have a trained and certified technician run the diagnostics to correctly make hybrid car repairs. As you can probably guess, that training and certification costs, and they are going to need to recoup that expense. 

So, we’ve had talked about some downsides to hybrid car repairs and ownership.  But like anything, there are both hybrid car pros and cons, so we offer you these offsetting pros of a hybrid car:

• Minor maintenance can be a DIY job because it has the combustion engine. Those minor maintenance things are basic like fluid checks, air filter and fuel filter replacement, and changing the spark plugs.
• A money saver when it comes to gasoline purchase with many of the hybrid cars that have an auto-shutoff for the combustionable engine and runs on the electric power. When it shuts the engine off and goes all electric at signal lights, it eases the strain on the engine. 
• Brake system last longer with the regenerative braking system that most hybrid cars have. This new brake system reduces the wear and tear on the brake system and recharges those expensive battery packs. .

What is the maintenance cost of a hybrid car?

A hybrid car’s  basic maintenance on the internal combustion engine is close to the same on a regular car like oil changes. However, the big upside to hybrid car maintenance: It will go 80,000 miles before it needs a real service.  That is up to 5 years unless unexpected hybrid car repairs are needed. 

Then the cooling system is another factor to consider in hybrid car maintenance due to the technical aspect. First of all, you’ll pay for the technician’s training because not just any mechanic can do hybrid car repairs or maintenance. Thankfully though, the cooling system is good for 100,000 miles before a replacement is needed. 

What happens when a hybrid car runs out of battery?

Well, if it is the larger of the 2 battery packs, you’re walking. The smaller battery operates the car’s electronics and won’t affect you’re driving the car. However, the larger battery pack in a hybrid car is a must have for the car to operate, with the exception of 2 models: The Ford Fusion and the Toyota Camry Hybrid.

What is the difference between a hybrid and an electric car?

They both use electricity, right?  The basic difference is an electric car runs only on electricity it gets from a battery that has stored energy. A hybrid car runs on both electricity from a battery pack and a combustion engine using conventional fuel.

What is the cheapest hybrid car available?

Checking 2021 pricing for traditional hybrids, your 4 cheapest are as follows: 

• Ford Maverick Starting Price: Start Price $19,995
• Hyundai Ioniq Hybrid Starting Price: $23,400
• Hyundai Elantra Hybrid  Starting Price: $23,550
• Toyota Corolla Hybrid Starting Price: $23,650

Is it better to buy a hybrid or electric car?

If your main goal is for gas saving and fuel efficiency, both hybrid and electric cars are going to save you money.  Additionally and maybe even more important, both will get you federal income tax rebate and depending on where you live, state tax credit too. What about carpool credit? If your state offers tax credit for carpooling, both will get you the same tax credit.
