Where is the camshaft position sensor “A”?

The camshaft sensor "A" is on the right cylinder head in the front, but I need to tell you this might not be the problem, as the timing chains wear the PCM will throw this code letting you know the camshaft is not where it is suppose to be due to the "slop" in the timing chain so if you change the sensor out and you still have this issue you know he timing chain/guides/camshaft phasers/tensioners need to be replaced. Please what this video to show you how.

Here is the location of the sensor. If the engine makes a slight rattling sound at idle, this may be the problem. Please upload a short video in your response of the problem, so I can see what's going on. Check out the images (below). Ken
