Camshaft Position (CMP) Sensor
CMP sensor is a Hall Effect magnetic switch. The Hall Effect switch is activated by a single vane, which is driven by the camshaft. On models with Electronic Ignition (EI), CMP sensor is mounted on back of cylinder head. On models with Distributor Ignition (DI), CMP is located inside distributor. On all models, CMP sensor provides cylinder identification information during engine start-up for PCM to initiate correct firing order.
Crankshaft Position (CKP) Sensor
CKP sensor is a Hall Effect magnetic switch. The Hall Effect switch is activated by vanes on the crankshaft damper and pulley assembly. The Profile Ignition Pick-up (PIP) is a crankshaft position signal that is sent to the PCM. The PIP signal generated by the Hall Effect sensor provides base timing and RPM information to the PCM.
