Where is the camshaft position sensor on a 2007 4.7L Dodge truck engine?

The camshaft position sensor (CMP) on a 2007 Dodge 4.7L engine is located on the front of the engine, near the passenger side, on the cylinder head. It's usually mounted fairly close to the timing chain cover.

However, it's best to consult a repair manual specific to your year and model Dodge truck. The exact location might vary slightly depending on specific engine variations. A diagram in the manual will give you a much more precise visual location than a general description. You can find these manuals online or at auto parts stores.
