Location of the Camshaft Position Sensor on a 2000 GM 4.3L V6 Vortec engine?

The Camshaft Position Sensor (CMP sensor) on a 2000 GM 4.3L V6 Vortec engine is located on the passenger side of the engine, near the rear of the cylinder head. It's typically mounted on the cylinder head itself, fairly close to the camshaft, and often has a single wire connector. You'll likely need to look carefully, potentially using a flashlight, as it can be tucked away a bit.
