Engine power reduced means that the CPU has placed the ECM in a safe operating mode and reduced power to lessen the risk of serious engine / transmission damage. Stop and check oil level and coolant level at the radiator cap. have the fault codes read urgently so as to prevent damage to the units

Sopunds like the computer has gone into a limp mode. You need to take it in for a professional diagnosis.

best bet is to stop in at a Pep Boys, Autozone, or similar big autoparts seller, and ask for free trouble code scan, which should pinpoint area causing problem. If not obvious by codes, what is necessary to repair the problem code, get back to us with those codes and we will be glad to assist you further. Better this way, takes away the guess work, and saves you money, as well as getting it right the first time.

The following is a post from another site. I had the same problem and this worked for me.

Hello all,

I just wanted to share with everyone with the problem that I had withmy 2003 1500HD Crew Cab with 6.0 Liter. My truck would go into reducedengine power off and on. Sometimes one a week, sometimes 5 times on a20 mile trip. My problem was a broken wire on the plug in going in tothe throttle body. In the picture is the plug in that had caused me allof my pain and grief....... My problem was very intermittent and washard to diagnose. I started vehicle and with all codes clear. I wiggledthe wiring harness in the picture and vehicle spit and sputtered,throwing it into reduced engine power mode, and then smoothed out to asmooth idle. I disconnected the plug and pulled wires out of plug endand found a broken wire. Mine was a brown wire with white stripe. BUT,what was interesting, was that this vehicle had apparently had the smaeproblem with previous owner, becuz there was another wire (yellow wire)right beside the one that I found broken already soldered up and tapedfrom where it had apparently happened before. This was my problem andnot my truck is running great, and actually even idles better thatbefore. Hope this helps with any problems that anyone else is having. Iknow this problem can be very irritating.

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.


how do you fix the "reduced engine power" light on the dash bard of a 07 Chevy Impala LTZ and "Service Traction Control"?

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.
