Check Engine Light Flashing and Traction Control Light On (Common Causes)

The TCS light and Check Engine light are two of the most common error lights that can come on in a car. They can be very confusing for drivers, as they often don’t know what they mean or how to diagnose the problem.

In this article, we’ll take a look at the meaning of these two error lights, how to diagnose the problem, and some of the common causes of these lights coming on.

Meaning of the TCS light

The TCS light stands for Traction Control System. This light comes on when there is a problem with the traction control system in the car.

This system is responsible for keeping the car from slipping and sliding on slippery or icy roads. When this light comes on, it means that the system is not working properly and the car may not have as much traction as it should.

Meaning of the Check Engine light

The Check Engine light is one of the most common error lights in a car. It can come on for a variety of reasons, but it usually means that there is a problem with the engine.

This light can be very serious, as it can indicate a problem that could lead to the car breaking down.

How to diagnose the problem of these two error lights?

The OBD2 scanner is a tool that can be used to diagnose engine light and traction control light problems. The scanner can display two different error codes: PO856 and PO858. These codes indicate that there is a problem with the on/off switch or wiring.

Often, these lights will come on due to a simple problem that can be easily fixed. However, they may also come on due to a more serious problem. In either case, it is best to have the car diagnosed as soon as possible.

Common causes of Check Engine and Traction Control lights coming on

There are a few common reasons why these lights might come on. One of the most common reasons is a loose gas cap. If the gas cap is not tightened properly, it can cause the Check Engine light to come on. Another common reason is a dirty air filter.

A dirty air filter can cause the engine to run less efficiently, which can trigger the Check Engine light. Lastly, a faulty oxygen sensor can also cause the Check Engine light to come on. This sensor is responsible for measuring the amount of oxygen in the exhaust, and if it is not working properly, it can cause the light to come on.

The cost to fix the possible causes with the Check Engine light and Traction Control Light

The cost to fix these lights can vary depending on the problem. If it is something as simple as a loose gas cap, it will usually just cost the price of a new gas cap to fix the problem.

However, if the problem is something more serious, like a faulty oxygen sensor, it can cost upwards of $200 to fix.

Frequently Asked Questions

What should I do if either of these lights come on?

If either of these lights come on, the best thing to do is take the car to a mechanic to have it diagnosed. They will be able to tell you what is wrong and what needs to be fixed.

What are some of the common causes of these lights coming on?

Some of the common causes of these lights coming on are a loose gas cap, a dirty air filter, or a faulty oxygen sensor.

How much does it cost to fix the problem?

The cost to fix the problem can vary depending on what is wrong. If it is something as simple as a loose gas cap, it will usually just cost the price of a new gas cap. However, if the problem is something more serious, like a faulty oxygen sensor, it can cost upwards of $200 to fix.

Why is my check engine light flashing and my traction control light on?

If your check engine light is flashing and your traction control light is on, it’s likely that there is a problem with your vehicle’s engine or transmission. However, it’s not always easy to determine the exact cause of the problem.

Will a misfire cause traction control light to come on?

A misfire can cause your traction control light to come on, but it isn’t always the only reason. If your traction control light is on, it’s important to have your vehicle checked by a mechanic to determine the cause.

What does it mean when traction control light flashes?

When your traction control light flashes, it means that there is a problem with your vehicle’s traction control system. This could be caused by a variety of factors, including a malfunctioning sensor or a problem with the system itself.

Does traction control reduced engine power?

Yes, traction control can reduce engine power. This is usually done to prevent the wheels from slipping, especially on slippery or icy roads.

Does traction control affect transmission?

Yes, traction control can affect transmission. In some cases, traction control can cause the transmission to shift into a lower gear to prevent the wheels from slipping.

How much does it cost to fix a traction control system?

The cost to fix a traction control system can vary depending on the problem. If a sensor is malfunctioning, it may be relatively inexpensive to replace. However, if the system itself is damaged, it could be more expensive to repair.

What causes traction control to malfunction?

There are a number of factors that can cause traction control to malfunction. This can include a problem with the system itself, a sensor that is not working properly, or a problem with the vehicle’s engine or transmission.

What sensors can cause transmission problems?

A variety of sensors can cause transmission problems. This can include the speed sensor, the transmission fluid sensor, or the transmission pressure sensor.

What are the symptoms of a failing speed sensor?

A failing speed sensor can cause the transmission to shift erratically or not shift at all. Other symptoms can include the check engine light coming on or the vehicle’s speedometer not working properly.

What happens when your transmission sensor goes bad?

When your transmission sensor goes bad, it can cause the transmission to shift erratically or not shift at all. This can lead to the check engine light coming on or the vehicle’s speedometer not working properly.

How much does it cost to replace a transmission sensor?

The cost to replace a transmission sensor can vary depending on the type of sensor and the make and model of your vehicle. However, it is typically a relatively inexpensive repair.

What are transmission codes?

Transmission codes are numbers that correspond to specific problems with the transmission. These codes can be used by mechanics to diagnose problems with the transmission.

How many transmission sensors are there?

The number of transmission sensors can vary depending on the make and model of your vehicle. However, most vehicles have at least two or three transmission sensors.

Is a speed sensor easy to replace?

A speed sensor is typically a relatively easy repair. However, it is important to note that the sensor is located in the transmission, so it may be necessary to take the vehicle to a mechanic to have the sensor replaced.

Conclusion

If you see both the check engine light and traction control light come on while driving, don’t panic. There are several reasons why this can happen, and in most cases, it is not a cause for alarm.

The most common reason for both lights to come on are problems related to a faulty traction control system, such as wheel speed sensors or low tire pressure. You can use an OBDII scanner to read and reset the error codes thrown by the computer. If the light comes on frequently or stays on after the engine has been restarted, then there could be a problem that needs to be addressed by a mechanic.
