SOURCE: The reduce power light comes on and the check
the 1st thing u need to do is have the system tested for the trouble code that is stored when the check eng light comes on, that will lead you in the direction of the problem
SOURCE: Reduced power code comes up and my truck stalls.
I had the same problem, and the solution was cleaning the throttle body, it does need to be completely removed to be cleaned thoroughly. I just used some brake cleaner on a rag to clean off all the carbon deposits. A friend of mine who is a dealer tech had only seen this trouble code once, and this was the solution. So far, my light has not come back on and the truck is running alot better at idle.

hi there my name is don i will try to help you on this
when your reduced engine light comes on that means there is a active fault code in one of the sensors that is cusing this
you will have to get it scanned or retreive the codes from the dash
once you shut it off and turn it back on it temporarly resets until the diagnostics go through it again and it will reduce the power to the engine
it could be something simple like a gas cap or tire pressure but you will have to get it scanned to find out
thanks
don
SOURCE: reduced power
This is what is called 'limp mode', the computer detects a problem, and to avoid damage to the vehicle, limits the power, and kicks on the check engine light. Bring it to a parts store where they will plug a hand held scan tool into the truck's diagnostic port, check for codes stored in the computer, and tell you what they are, what they mean, and suggest a fix(es) for the problem. This is a free service at most stores. If you still have questions, post them and the codes here for further help.
SOURCE: What does reduced engine power light mean
this model has what they call fly by wire.. no accelerator cable. If the computer detects a problem in the thottle system it will not allow the engine to accelerate and will show reduced power and possibly set a check engine light. The dealer usually wants to replace the throttle assembly which is very expensive and usually un nessesary.
I have had a lot of succes with just cleaning the throttle plates real good.
