Crankshaft Position Sensor: Description and Operation

Crankshaft Position Sensor

PURPOSE

The Electronic Control Module (ECM) uses this input to determine engine speed and TDC, and adjusts ignition timing, fuel injection, and idle
speed accordingly. 

OPERATION

Power is supplied to the camshaft position sensor from the MFI relay and is grounded to the body.

The sensor generates a pulse signal, as it repeatedly connects and disconnects between 5V, supplied by the ECM, and ground.
