I would like to know where the camshaft position sensor is located.

I read that occasionally oil seeps under the lifters holding the valves open, preventing compression. Possible solution is hold it to the floor and keep cranking till it starts. I read possibly as long as 80 seconds but dont crank it more than 120 seconds to avoid starter damage. Otherwise cam sensor should be held on cylinder head with a single bolt. Its a small black plastic sensor with wire attached.Most likely toward rear/transmission side of engine. Hope this helps Joe, Dave Gold
