Camshaft Position (CMP) Sensor

On 5.2L, CMP sensor is located inside distributor and is made up of a Hall Effect device (sync signal generator) and a rotating pulse ring (shutter) on distributor shaft. This sensor reads slots in cam timing sprocket. PCM uses this information along with information from Crankshaft Position (CKP) sensor to determine if fuel injectors and ignition coils are properly sequenced for correct cylinders.
