Crankshaft Position Sensor

The Hall Effect type crankshaft position sensor is mounted on transaxle bellhousing. The sensor reads slots (4 per cylinder) on flywheel/flex plate. The signal generated provides engine speed and crankshaft position information to engine controller. The engine controller uses this information to determine proper fuel injection and ignition timing.

When a flywheel/flex plate slot passes the crankshaft position sensor magnet, output voltage of the Hall Effect sensor goes high (5 volts). When the metal between the slots is aligned with sensor, output voltage goes low (.3 volts).

This high/low voltage signal is generated and sent to engine controller each time one of the slots passes the crankshaft position sensor. The engine controller uses this information to determine when to energize the injectors for fuel delivery to the proper cylinders.
