Where is the cam shaft sensor on 3500 2006 dodge sprinter?

The camshaft position sensor (CMP sensor) on a 2006 Dodge Sprinter 3500 with a Mercedes-Benz OM647 engine (the most common engine for that year and model) is located on the top of the engine, near the front of the cylinder head, on the driver's side. It's usually fairly accessible once you get past the various engine covers and hoses.

However, the exact location might vary slightly depending on the specific engine configuration. A repair manual or a diagram specific to your vehicle's VIN number would be the most accurate resource for pinpointing its exact position. You can find these diagrams online through sites specializing in car repair information, or at a local auto parts store.

Important Safety Note: Working on engine components requires mechanical aptitude and safety precautions. If you're not comfortable working on your vehicle, it's best to take it to a qualified mechanic.
