SOURCE: 2001 GMC YUKON REDUCE ENGINE POWER ON MESSAGE BOARD

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.

Your engine has reached it service period. You will need have it serviced, change engine timing belt, point plugs oil etc. snd then have the brain reset using a diagnostic tool!

SOURCE: i have a 2008 chevy silverado and was going down

This is a 'limp home mode' and is engaged if a fault is detected that may result in damage to the engine if allowed to go unchecked. Take the vehicle to a dealer or Autozone and get a read out of the stored error codes from the on-board diagnostics module as this will help define the exact nature of the fault.

SOURCE: The reduced power engine light comes on and the

This light comes on when a problem occurs with the throttle body assembly or the electronic pedal assembly. If their is dirt,mud, or moisture in any of the connections where the harness plugs in it can make this happen. If it has alot of miles on it the electric motor that controls the throttle may have too much play and bind under acceleration. The motor is not serviceable and may require replacement. The pedal assembly also is non-serviceable.

Reduced power and service stabilitrack on my 2007 equinox.


The reduced power light is most likely responsible for the stabilitrack light to illuminate as it will shut it down as a safety feature. The reduced engine power light is normally set by a defective throttle control motor. In some cases, the sensor on the gas pedal can also cause this message to display, but, in my experience, the throttle control motor is most likely the problem.

On my 2010 Silverado the message center says engine power reduced, service stabilitrack and service traction control system. What would cause these messages. It started after sitting for a few days


The fault codes have nothing to do with it sitting for a few days. There are sensors that work with your ABS brakes and TCS to help your car maintain control when corning briskly under load. You probably have a bad sensor on one of the wheels. Recommend you get the Haynes manual to see exactly how to test and replace them. A multimeter will help too.

I drive a kenworth t600 tractor. Engine shut down while driving no power glided to side of road what would cause the engine to shut down in mid stride


Check coolant level or possibly a bad coolant level sensor. If either of these are at fault, it can cause the engine to shut down or run with reduced power to keep from damaging the engine. Had this problem with a 2005 Freightliner w/ Detroit engine. (bad coolant level sensor)

Why does the engine shut off on 2006 hhr when message engine power reduced displays


Could be something causing the engine to die which is making the warning light come on, or something that the computer sees as a threat of damage to the engine and the computer is shutting down the engine to prevent damage.
You would have the computer scanned for trouble codes and then proceed with troubleshooting the issue.
