Not being sure how this worked I was very brief on the question. I pulled the code with my ODB II reader and the full text is: "Camshaft Position A - Bank 1 Circuit Malfunction". Is that consistent with your recommended soltuion above?

Yep, same solution. Let me know if you need anything else, thanks again.

Is there a part number for this or do I just ask for the CMP sensor?

Here is the part number if you buy it from the dealership otherwise just ask for the camshaft position sensor. Let me know if you need anything else, thanks.
