2002 grand prix gt issue
05-31-2012, 06:50 PM
Hello, I have a 2002 Grand Prix GT with a few problems. The ABS and Trac Off lights are on. Also, the car will randomly turn off while im driving. Lastly, and more recent, the shifter gets stuck in park and I have to push in the Shift Lock Release button. Could someone help and tell me the reasons for this happening? Thank you!

Welcome to AF.
The trac-off and ABS lights are most likely due to a bad wheel speed sensor. They are an integral part of the hub bearing assemblies, and cannot be replaced separately from the hubs. An ABS capable scan tool will be needed to narrow down which wheel is causing the lights if that is what it is, and would also detect a problem with the ABS pump and/or module which could also trip these lights.
The car randomly shutting off and the shifter issue are most likely caused by a bad ignition switch/harness, a common problem with these cars.
