Crankshaft Position Sensor: Description and Operation
SYSTEM OPERATION
Crankshaft Position Sensor - Typical
The crankshaft position sensor is mounted to the transmission bellhousing at the left/rear side of engine block.
Engine speed and crankshaft position are provided through the crankshaft position sensor. The sensor generates pulses that are the input sent to the
Powertrain control module (PCM). The PCM interprets the sensor input to determine the crankshaft position. The PCM then uses this position,
along with other inputs, to determine injector sequence and ignition timing.
The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel within a certain distance from it.
