Go to your nearest Auto Zone store and have them put their computer on your vehicle, to see what code comes up (IT FREE). They should let you know what the problem it...if not....let me know what the code is and I will let you know what is wrong..Hope this helps you ??

My 2005 chevy cavalier has a service engine, abs, and trac off light on. sometimes the low trac light comes on when in the reverse position, then switches to the 3 lights when put in the drive position....


The ABS and traction off lights usually indicate a bad wheel speed sensor. I can't remember if the service light came on the three times mine went. The most common one to fail is the left front.

Try this cheap fix first.

Remove the left front wheel speed sensor, clean and reinstall it. They are magnetic and some times road debris will block the sensor. If that was the problem the ABS and traction lights will go off when you start the car.

Your second option is to have the shop scan the vehicle trouble codes, usually this costs an hours labor.

Hope this helps

What does the low traffic light mean in a 1998 chevy cavalier?


If your ABS light is on as well, have a shop scan it (it requires a special scanner). If it's just your Trac light without ABS, it is most likely a sensor under the hood at fault. If you are getting a check engine light as well, get the codes read!
This happened to me without an ABS light and it was the upstream O2 sensor. The reason it throws the Trac light is because if any components that the traction control uses (ignition, fuel) are affected by a bad sensor, the PCM shuts down traction.
In fact, when I replaced the O2 sensor, a handful of other little issues resolved as well.
If you do have an ABS light on, it could very well be a wheel speed sensor.

2000 chevy cavalier ABS and Brake lights staying on


You had it scanned? They didn't find any codes? If there were no codes, did the ABS computer even communicate? Also did you check the brake fluid, most newer cars have a float switch in the master. If the fluid is low that will set off the lights.

Enhanced Traction System Warning Light (TRAC OFF)


Sometimes it's a complaint with the ABS braking system. If it comes on and you have no other problems and stays on for while, check your brakes. I have had this issue before and had my brakes replaced. They were worn but for some reason were not squeaking.
