traction control problem

Hello,

It sounds like you have a front axle bearing that is going out which houses the ABS sensor. This will cause the ABS light to come on and the car to catch and hesitate.

Here is a guide to show you what you are in for when doing the job.

I recently changed my spark plugs and I soon noticed my advtrac light is on. Could I have bumped or disconnected anything or is this unrelated? I worked in a GM dealership and still do my own work. What should I look for or is this a dealer only fix? Thank you, Scott Berger.

Yes, this happens when you have a front ABS wheel speed sensor that is out. You can scan the system to see which one it is or just look for the one that got disconnected during the job.

Here is a video to help you see how to scan the system:

This guide can help you test the sensor without a scanner.

Please let us know what happens.

Thanks you for the guides. I had a right front wheel sensor go out which caused the problem. I got a new one.
