Having problems with your 2003 GMC Sierra 2500HD ?
Can't find throttle position sensor on 2003 gmc sierra 2500hd. the part store gave me the part, but i can't locate anything that looks similar on my truck.
From what I'm reading, it looks like you have an accelerator pedal position sensor instead. Look under the dash to see if the part goes there.
