#32 of 34 2002 Cavlier Electrical Problems by ak23x Jul 20, 2009 (8:09 pm)
I have a 2002 cavalier that has been in a front end collision and it has some electrical problems, [the cd player doesnt work and sometimes when i turn on the brights i get some interference and i get a buzzing noise in the speakers] the check engine and trac off light have been on since i bought the car... i took the speakers out of the car to see if they worked and they do work, and i used a voltage tester on the wiring up to the front speakers and im getting a reading but since the airbag went off in the collison[before i bought the car] im afraid to take the dash off... what can be done to the cd player? and can i reset the check engine/trac off without taking it to a shop?

Replying to: morris2008 (Apr 12, 2008 9:40 am) If you have the Trac Off light coming on at random times and the transmission jumping into low gear here is the answer:   Replace the TPS (Throttle Position Sensor). $30 to $40 if you do it yourself or $70 to $95 if you have a service station do it. Of course you can pay a dealer to do it but they will charge you hundreds of dollars, (just my opinion). This will fix all of your problems related to the TRAC OFF light and transmission shifting into low gear.
