2000 Chevy Cavalier 4 cyl Two Wheel Drive Automatic 130xxx miles

Hi, I have a problem with my cavalier 2000. I have on my dash board the "check engine" light n the "track off" light. I made the "TPS sensor" replacement but everything still the same. The funny thing to me is that the car "still working fine" n I been driving the car like for about a year ago like that, n still working fine. What it could be the problem? Somebody told me that the TCM (transmission control module or traction module control) that can be the problem! But I dont know what is that n where is located! Thanks for any great help!

I would scan the vehicle for an ABS codes first, any ABS codes will disable the ETS(Enhanced Traction System). Or an engine code.I would start there first before any other parts are put on, Traction Off
The IPC illuminates the traction off indicator when the following occurs:

" The electronic brake control module (EBCM) inhibits the traction control system. The IPC receives a class 2 message from the EBCM requesting illumination. The traction control system is disabled when the following occurs:

- For Chevrolet only, the shift lever is in FIRST (1) or SECOND (2) gear. The EBCM receives a class 2 message from the powertrain control module (PCM) indicating the gear position.

- For Pontiac and Oldsmobile only, the body control module (BCM) detects that the traction control switch is pressed (signal circuit is low). The EBCM receives a class 2 message from the BCM indicating the switch status.

- The BCM detects that the park brake is engaged (signal circuit is low) and that the engine is on. The EBCM receives a class 2 message from the BCM indicating the park brake status.

- The PCM detects certain malfunctions and is unable to perform torque reduction requests from the EBCM. The EBCM receives a class 2 message from the PCM indicating that traction control cannot be performed.

" The EBCM detects a malfunction in the traction control system. The IPC receives class 2 messages from the EBCM requesting illumination of both the service vehicle soon and traction off indicators.

" The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.
