Reduce Engine Power Indicator

(2004 GMC Yukon XL 2500)
My reduce engine power warning came on and the throttle was disabled. The engine was not overheating but I did replace the water pump and changed the oil. The warning light is still on and and throttle is still disengaged. I cant find any other problems with the engine. It idles fine with no leaking any where. Is there a reset for that warning indicator?

no. the problem has to be fixed. it is an issue with the throttle body unit. either the pedal sensor or throttle sensors are malfunctioning. you need a shop to tell you the problem and give you a bid

most likely the throttle body sensor. Mine went out on my 03 and it cost about $600 to replace at the dealer 3 years ago. You may get a better price outside of the dealership and a reduced part cost today.
