On a 1998 Ford Ranger 2WD with a V6 engine, the camshaft position sensor (CMP sensor) is typically located on the
passenger side of the engine, near the
front of the cylinder head. It's often mounted directly to the cylinder head, but sometimes sits in a bracket very close by. It's a fairly small sensor with a single wire connector.
However, the *exact* location can vary slightly depending on the specific engine (e.g., 3.0L Vulcan vs. other V6 options). Consulting a repair manual specific to your engine's year, make, model, and engine code is recommended for pinpoint accuracy. A diagram in the manual will be invaluable.
