Crankshaft Position Sensor: Description and Operation
Hall Generator
Standard Wave Pattern
PURPOSE
The Crankshaft Position and the Camshaft Position Sensors create square wave signals used by the ECM as reference for ignition and fuel
injection timing.
OPERATION
-
The crankshaft position sensor detects the crank angle (piston position) of each cylinder. converts it to a pulse signal and inputs it to the engine
control module. The engine control module computes the engine speed and the intake air amount for one stroke and outputs the injector drive
signal and injection command signal based on this signal.
-
Power to the camshaft position sensor is supplied from the MFI relay and the ground is located in the body.
