The camshaft position sensor (CMP sensor) on a 2002 Ford F-350 with the 7.3L Power Stroke diesel engine is located on the
passenger side (right side) of the engine, near the front of the engine block. It's typically mounted on the valve cover, fairly close to where the distributor would be on a gasoline engine (though the 7.3L doesn't have a distributor). You'll likely see a single-wire connector attached to it.
It's best to consult a repair manual or online diagrams specific to the 7.3L Power Stroke for your exact vehicle year to be absolutely certain of its location before attempting any work. Visual inspection with the engine cover removed will confirm its position.
