On a 2000 Jeep Wrangler 2.5L, the camshaft position sensor (CMP sensor) is located on the
passenger side (right side) of the engine, near the front of the cylinder head. It's usually mounted fairly close to the camshaft itself, but its exact position might vary slightly depending on the specific engine configuration. You'll likely find it near the distributor (if equipped) or in that general area.
To be sure, you should consult a repair manual specific to your vehicle year and engine. A diagram will help immensely in pinpointing the sensor's location. A visual inspection with the engine cover removed will help confirm its location.
