Where are the camshaft position sensor located on a 2003 GMC Envoy and how do you replace it?


number 2 is the camshaft position sensor, number three is the camshaft position actuator

From my understanding th replacement is pretty easy. I have not replaced one, so I wont try and tell you how to replace it, however check out www.trailvoy.com for answers to any Envoy/Trailblazer question.
