Where is the Camshaft position sensor located?

Yep, I must tell you that the sensor may not be the problem, most of the time when you get camshaft codes it is because the timing chain, guide or camshaft actuator nee to be replaced, but you need to make sure the engine oil is clean and full, this can effect the codes as well. Does the engine make a slight rattling sound at idle? If so this can be the problem. Here is the location of the sensor so you can swap it out.

Bank 2 is on eh drivers side of the engine and sensor A is for the intake camshaft. It looks like you will need to remove the intake manifold. Check out the images (below). Let us know how it goes.
