Tranaction control wont go off

SOURCE: Check engine light on, traction control disabled

disc connect battery for 15 min. see if that will reboot cpu

SOURCE: my traction control disabled light is going on and

you may have a bad mass air flow sensor. engine goes into protection mode when this happens so it doesnt damage the engine. or your throttle position sensor is failing as well. best thing to do is check and seeif you have a check engine light on and have the code read.

i i have the samething here just reset the computer and the engine sign should go away its with the tc theres something wrong with it and it makes the computer seperate some part or disable which the transmission cannot work properly and the sign comes up for both
i learend ffrom sources from the internet.

SOURCE: 2004 grand prix no go with traction control light on.

My car is doing exact same thing! I flushed radiator and now I have traction control light, reduce engine power, and enigine light coming on! My car sounds like **** and won't idle and no power! 04 prix gt of course. It was fine until I flushed radiator and put new thermostat in! What do I do?

Hi accannaday,
Thank you for requesting me to help you with your problem.

The lights you described are warning lamps that are telling you that there is a malfunction in one or more of the HUNDREDS of systems and electrical circuits in your vehicle. Nobody can help you with this problem (including myself) until you have your computer network in your vehicle scanned for Diagnostic Trouble Codes (DTCs). Without these codes nobody can do any more than "GUESS" what the problem is. On the other hand, although I cannot tell you for certain what the problem is, I can explain some things to you and make a pretty good "educated guess".

Your check engine light is telling you that there is a fault in your engine control system and the Trac Off light is telling you that there is a problem with your Antilock Brake/Traction Control system. Certain faults can cause engine damage or destroy your catalytic converters (high-dollar if you have to relace them). The reduced power indicator is telling you that the engine control module has gone into reduced power mode to protect your engine and catalytic converters from damage. If ANY of these lights are on while you are driving the vehicle there will be DTCs set. (I know you said that you tried to pull up codes and didn't get any...please read on...)

First, please note that what I said above is "computer NETWORK". There are several different computers or "modules" in your vehicle. They are all connected together and share data with each other. They actually share data from several sensors and inputs, but we are going to talk about your wheel speed sensor data for a minute.

The ABS/Traction Control system uses data from the wheel speed sensors to determine when a wheel is slipping or locking-up on slick roads. The ABS will use this data to relieve the brake pressure on the slipping wheel to get it rotating again for better control and stopping ability. At the same time, if the slipping is severe, the traction control activates and sends data to the engine control computer. The engine control computer can shut the fuel and ignition off to reduce the torque on the drive wheels in an effort to regain control. When this occurs under normal conditions with a slipping wheel, the TRAC light will illuminate for a few seconds and go back off when control has been achieved.

Here's the problem:
If the wheel speed sensor fails or is producing an erratic signal to the ABS module, it can actually cause continuous cylinder misfire due to the engine computer turning the injectors and ignition coils on and off and on and of and...you get the picture.... Anyway, this type of operation can produce engine damage and wreck your converters....This is where the reduced power mode comes in.

When in reduced power mode, the engine will supply only a pre-determined amount of fuel and will limit the accelerator from working and will only allow the vehicle to be driven up to a set maximum speed. It takes "manual control" of the system so that you can still drive the vehicle to get it repaired. (You might want to take the back0roads when this happens because it will not accelerate very well and it is a good way to get run over.)

I hope I haven't bored you too much with the details. I told you all of that so you can understand this:

Your wheel speed sensors on your vehicle are built into the wheel bearing and hub assembly. I think you may have damaged your wheel bearing and/or wheel speed sensor when you bent your wheel.

This can be verified by scanning your computer system. Please note that if you are using a generic OBD2 code reader, you will NOT be able to access these codes. Generic OBD is only for emissions-related engine and transmission control faults. Where you are most likely to find the codes that will be needed to properly diagnose and repair your Pontiac will be located in the ABS/Traction Control module.

You will need a scan tool that has the ability to scan your entire network and display live data streams to verify the actual cause of the problem as well as to reset the memory in all of the affected modules after repairs are made.
