Hey jcowart,

Got the same truck and the same problem. It did it today and quit after i restarted it. The engine light symbol was on, and after i wiggled it i noticed it wasn't on anymore? Did you replace the whole wiring harness, or just repair (recrimp or resolder) the wires in the plug?

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.

SOURCE: reduced power for real!!!!

I had the same thing happen to me yesterday. Sitting at a light, went to accellerate and would barely move. The same lights came on for me too. I had it towed to the Saturn dealership and they tell me it's the computer control for the transmission. It's going to cost me in excess of $950.00 to replace. I did a little research and apparently this is an ogoing problem with 2003 Vues.

I just got my alternator fixed then i started having the ESC serv ice light come on, and the trac symbol comes up and the engine light flashes. and the power is reduced and it jerks when driving


its possible that the incorrect voltage regulator was fitted to the alternator during the repair. A low voltage or irregular voltage from the alternator can cause havoc with vehicle electronics

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.

What causes the "Reduced Engine Power", "Service Stability Control" and "Traction Control" warning lights to come on?


the "Reduced Engine Power", problem causes the PCM to disable "Service Stability Control" and "Traction Control" turning on the warning lights to come on for those systems . The reduced engine power is because of a problem with the electronic throttle control system or as GM calls it TAC system . Reduced Engine Power Mode
When the PCM detects a condition with the TAC system, the PCM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
• Acceleration limiting--The PCM will continue to use the accelerator pedal for throttle control, however, the vehicle acceleration is limited.
• Limited throttle mode--The PCM will continue to use the accelerator pedal for throttle control, however, the maximum throttle opening is limited.
• Throttle default mode--The PCM will turn OFF the throttle actuator motor and the throttle will return to the spring loaded default position.
• Forced idle mode--The PCM will perform the following actions:
- Limit engine speed to idle by positioning the TP, or by controlling the fuel and spark if the throttle is turned OFF.
- Ignore the accelerator pedal input.
• Engine shutdown mode--The PCM will disable fuel and de-energize the throttle actuator.

Reduced engine power warming came on yesterday, after driving in extreme cold temps, idled rough and the. started back up fine after sitting a few minutes. Drive today, in cold temps again, and drove...


Well...my ball park guess on this is just a tune up. The engine light is usually showing a misfire. If the plugs are bad then the cylinder is not igniting the fuel and it is flooding out. With what is here this makes sense to me. Let me know what it does turn out to be.

My stabalink trac light came on and the engine light came on saying it was reducing power, it felt sluggish and went about 30 mph.


{: ) The stabiltrak light is just an after effect of the check engine light. When the system detects inconsistencies with the accelerator pedal position and throttle position sensors, it will enter into "Limp Mode", engine power will be reduced and you cannot accelerate normallly as you expected. So that you can LIMP your way back home, or to a nearest service shop. A P2138 code may be set, or its conjunctions. Before you decide to have it serviced, if you have the time, try to disconnect the connector at the accelerator pedal. Check for any backed out terminals. Then reconnect again firmly. When you hear it clicks in, it's firmly seated. Testdrive. If not okay, you do the same thing to the throttle position connector. It's on the side of the throttle body. I hope you get lucky.

Check engine and TRAC warning lights are on. I


it won't hurt to drive it, as a matter of fact on dry pavement it never engages, but it will cause wheel slip in rain or snow, you don't need it but its nice to have
