Crankshaft Sensor
A dual Hall Effect crankshaft sensor, mounted at crankshaft pulley, is used on 2.3L dual-plug Distributorless Ignition System (DIS). 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 PIP signal, monitored by DIS ignition module to provide RPM signal to ECA. The second switch produces CID signal, used by DIS ignition module to identify which coil pack to trigger. If CID signal is not present, vehicle will be hard to start.
