SOURCE: WHat does it mean when your traction control

Hello Jeremy.
When your traction light comes on it is indicating wheel spin on acceleration. To prevent wheel spin an onboard computer reduces engine power to limit the wheel spin. Some, if not most, cars equipped with this feature will also apply the brakes if wheel spin continues after reducing engine power.
Hope this answers your question.
Thank you for using Fixya!

SOURCE: reduced engine power on

The traction control uses the speed sensor in the transmission and the wheel speed sensors to determine wheel spin. If a wheel spins braking is applied to it so that the power can be transferred to the other wheels. At some point the ECU detected a gross disagreement between the sensors and so as a precaution has entered into a limp home mode. On some systems if the fault is in error it can be cleared by putting the car into drive and moving forward a meter, putting in reverse and going a back a meter and doing this three times. If one or other of the sensors are faulty this process will not allow the error to be cleared. You need to check or have checked the error codes and the speed sensors.

2012 Buick Enclave, dash reads Traction control off, service stabilitrak. Engine power reduced... why????

Engine power reduced... is the main problem ,this turned off Traction control off, service stabilitrak. Your vehicle has electronic throttle control , The Gas pedal has sensors inside which are connected by electrical circuits to the PCM - engine computer ,the PCM use's these inputs to control the throttle plate by use of a 12 volt DC motor . Plus there are position sensors on the throttle body for feed back to the PCM. When one of these signals is off The PCM will put the system into reduced power mode . This will also set DTC'S - diagnostic trouble codes . Your best bet , take it to a qualified repair shop.

Malibu hybird 2008 /service traction /engine power reduced

Your best bet would be to take it to a qualified repair shop. Special tool's and knowledge are needed . Scan tools , electrical diagnostic , service information . Your vehicle has a bunch of computers (control modules) C.A.N. cantroller area network serial data communication networks . Hi speed , med. speed , low speed . The power steering is electronic ,computer controlled , sensors on the steering shaft .With those light's lit , DTC'S - diagnostic trouble codes are stored etc... Plus there is a real chance of being electrocuted. High voltage !

What does "Reduced Power, Traction Fault" mean?

GM's power strategy will reduce power if it doesn't see proper charging. It does this to conserve battery power by shutting off non-essential electrical accessories. It can also mean that the traction control system is reducing engine power to avoid a skid. The traction control system gets input data from the wheel speed sensors to figure out if you're entering a skid or the wheels are locking up. One way to get you out of the skid is to reduce engine power or pump your ABS brakes. In your case you should get the trouble codes read. An ABS or traction code code could be a C, U or B code which can't be seen by a cheap scan tool or the tools they use at auto parts stores. GM had major problems with the ABS wheel speed sensors built into the wheel bearing hubs in these vehicles. The fix involved replacing the hub. So get the codes read by a pro scanner to find out which wheel sensor is setting the code. Then do the fix. Also, the P0128 is usually caused by a bad thermostat. Fix that first, because if the engine doesn't get up to operating temperature, the computer can limit some features.

And not auto zone , pep boys , or advance auto parts . Thier diagnostic tool will not check codes in all system control modules .

Engine power reduced, service traction

when you have the fault codes read to find the exact sensor failure or cause , have it fixed then reset the ecm as the ecm will reduce the performance(limp mode) for safety reasons

Service Throttle Control

It sounds like these things are all related. When the a computer sees a problem in the Electronic throttle system, it will dissable traction control, and give the reduced engine power alert because the powertrain computer does not know the value of throttle postion.
Codes will need to be scanned in the computersto begin diagnosis.
