Crankshaft Position (CKP) Sensor
WARNING: This page is about a different car, the 1994 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
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.
