The Reduce Engine Power problem on my 03 Suburban went away when I had to replace the fuel mixing sensor. I damaged the sensor by topping off with E85 (ethanol) by mistake late at night. The vehicle just would not turn on in the morning. The vehicle had to be towed to the dealer. I was in Carlsbad NM about 800 miles from home. I had no choice but to pay $1,100 to get it fixed. At the same time the Reduce Engine Power problem went away. And thanks to God it has not come back for nine 9 months now.

SOURCE: Reduced engine power came on i'n my 00 chevy

Ok I would start by checking your shifter to make sure it adjusted right and you can do this by looking at your shift indicator if that is ok then might have a bad manual shift valve thats in the transmission, if that valve goes bad it would tell the pcm that your transmission is being shifted into another gear while your driving causing the Power control module (PCM) to out you vehicle into reduced engine mode

Why would my 2007 bmw 335i showengine fault warning running on reduced power


Is your oil level or radiator coolant level low? It sounds like the engine is going into "Limp Home" mode to save the engine.

Low engine power displays and in fact the vehicle barely moves


Could be the fuel pump in the Gas tank. Mine crapped out and caused the car to have reduced power for awhile before it quit all together.

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.
