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.

    Not good...408.00 repair bill on our end. I've had ours replaced 3 times!!!! Was told today that this should be the last, as service rep said about 6 months ago they final figured out that the wiring they were using for the controller was bad.

    It was actually indentified as a bad throttle controller

I have heard that the wheel speed sensor cable connectors get to be intermittent and cause this behaviour.

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 .

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.

The "engine power is reduced" light comes on
po455 is Probable Cause[s]

1. Defective, loose or missing fuel cap
2. EVAP canister broke, hose cracked or not connected
3. Purge or vent solenoid defective
4 . Vacuum leak at engine po121 code po121 means Throttle Position Sensor/Switch A Circuit Range/Performance Problem . it is usually indicative of a faulty throttle position sensor or faulty wiring harness in the engine bay.

WHat does it mean when your traction control indicator comes on and says it has reduced your engine power?
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!

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.
