Check engine light came on then reduce engine power


When this light comes on it means the computer control module has detected a fault in the system, it has reduced power to avoid any damage to the engine or transmission. You must now have the computer scanned for fault codes, this is done through the diagnostic connector under the dash see photo below.

Diesel. Reduce power lite turned on. Shut off engine and started back up - lite is off. Can it be driven?


Jerry, Drive to a good shop. So many things can cause reduced power light unfortunately. The first step would be to get the truck hooked up to a scanner/computer and have the computer scanned for trouble codes. One thing that you could try is to drain the water from the water separator that is mounted on the frame under drivers front door. If the PCM picks up on water, power is reduced until water is removed/drained. It could be an exhaust sensor that is reading faulty. Unfortunately from here its impossible to tell you exactly what the fault is because there are just so many engine sensor inputs that could cause your problem. Check the attached links, forums,instruction and guides, Good luck

Engine power reduced


Engine power reduced , problem with the electronic throttle control ! Watch a couple of video's on youtube , google GM engine power reduced . The gas pedal an the throttle body have position sensor's ,when the PCM/ECM - engine computer see conflicting input's from one of these sensors it send's into a reduced power mode . Your best bet mite be to take it to a qualified repair shop.
