Crankshaft Position (CKP) Sensor

A dual Hall Effect crankshaft sensor, mounted at crankshaft pulley, is used on 2.3L dual-plug Electronic Ignition (EI) system. Sensor signals are generated when 2 trigger wheels, mounted on pulley assembly, pass through air gap of 2 Hall Effect switches. One switch produces a Profile Ignition Pick-up (PIP) signal, monitored by DIS ignition module to provide RPM signal to PCM. The second switch produces Cylinder Identification (CID) signal, used by EI ignition module to identify which coil pack to trigger. If CID signal is not present, vehicle will be hard to start.

On Villager, CKP sensor is mounted inside distributor. Sensor uses a photo diode and Light Emitting Diode (LED) to detect engine rotation. Slits in a rotating disc indicate crankshaft position and RPM.
