Crankshaft Position Sensor: Description and Operation

CIRCUIT OPERATION
The Powertrain Control Module (PCM) supplies 5 Volts to the crankshaft position sensor on circuit K25. Circuit K25 connects to cavity A17 of the PCM.

The PCM receives the crankshaft position sensor signal on circuit K27. Circuit K27 connects to cavity A8 of the PCM.

The PCM provides a ground for the crankshaft position sensor (circuit K27) through circuit K4. Circuit K4 connects to cavity A4 of the PCM.
