I have a 2006 checy impala and the TCS ( TRACTION CONTROL SERVICE) liught came on..What does this mean?

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.

SOURCE: traction light on , reduce engine power lights on

I know this is not a solution but I too started having this same problem today. Start car, runs normal then all the sudden it feels funny, traction control light blinks on and dash displays service traction control-reduced engine power. This causes my car to sputter like it is going to stall I have to pull over and turn my car off and back on to drive off (only for it to do it within the next 10 minutes). I thought turning TC off would work for now just to drive it, no not successful stil does it : ( I TOOK IT TO AUTO ZONE AND HAD IT SCANNED HAD A CODE FOR GROSS EVAC LEAK AND SOMETHING ABOUT THE THROTTLE PLATE/BODY NOT SURE IF THAT IS RELATED BUT THAT ALL THE INFO I HAVE ON THAT.

SOURCE: my 2002 impala's service traction control light

Traction control only works when one wheel is spinning faster than the other it trys to even them out so it wont spin...sometimes if one of the wheels come off the ground in an uneven area or if you take a turn too fast and one wheel turns when the other one dont it is designed to operate.
I would remove all wheels and check the braking system...Is it 4 wheel disc or rear drum ?
If it has rear drums you could have a wheel cylinder leak that will sometimes lock the wheel because of fluid contamination....This would cause both lights to come on...If you find no problems
sometimes the abs sensor builds up fragments on the magnet and makes the light come on...
or if the abs sensor is not close enough to the exciter ring it will make the light come on because it will be out of adjustment.....all you do is press the sensor inward until it barely touches the ring and it will adjust itself....You can sometimes clean the magnet if it is contaminated and make the light go off ( only after you reach 6 to 15 mph. it will go off ).If it dont go off you have to buy a sensor.
Also make sure all tires have same amount and plenty of air to keep vehicle in balance/level.

Pretty much tells you the system with the fault

Traction Control is embedded into the abs braking
system, so diagnose that using the codes you have,
same as any other obd codes you get

The Reduced Power could be another problem & it

2006 chevy impala traction control


Reduced power is a problem with electronic throttle contol . drive by wire . Do you know what this is ? Taking the vehicle an having it hooked up to diagnostic tool an checking for DTC'S - diagnostic trouble codes is always a first step when trying to find the root cause of any trouble light ! And not auto zone , pep boys , or advance auto parts . Thier diagnostic tool will not check codes in all system control modules .

On my 2009 impala ls engine power is reduced keeps showing on the dash screen, as does service traction control. the car is running rough and has no power when this occurs.


You need to have the engine and body computers scanned for trouble codes to point you in the direction of diagnosing the problems.

Traction control light on and engine power reduced


you could have a stuck switch .....check your traction control switch on your dashboard....engage and disengage it , while paying attention to the rpms...notice any change...if you do notice a change, then replace the switch....if no change, it is probably on the trans itself and should not be a dealer only fix....your local reliable trans shop should be able to fix you up without emptying your entire wallet.

My 2009 chevy impala service traction light came on and then it said engine speed reduced


Have the codes checked. But you probably lost one of the wheel sensors. This will pop the light. When the ECM detects a wheel not move as fast as the others, it sets the light.

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.
