CRANKSHAFT POSITION SENSOR
OPERATION
-
The crankshaft position sensor functions to detect the crank angle (position) of each cylinder, and to convert those data to pulse signals, which
are then input to the engine control module. The engine control module, based upon those signals, calculates the engine rpm, and also regulates
the fuel injection timing and the ignition timing.
-
The power for the crankshaft position sensor is supplied from the MFI relay and is grounded to the vehicle body. The crankshaft position
sensor, by intermitting the flow (to ground) of the 5 V voltage applied from the engine control module, produces pulse signals.
