Crankshaft Position Sensor: Description and Operation

CIRCUIT OPERATION
The crankshaft position sensor is located on the right side center of the engine block.

Circuit K7 supplies 5 Volts from the Powertrain Control Module (PCM) to the crankshaft position sensor. The K7 circuit connects to cavity 17 of the PCM.

Circuit K24 from the sensor provides an input signal to the PCM. The K24 circuit connects to cavity 8 of the PCM.

The PCM provides a ground for the crankshaft position sensor signal (circuit K24) through circuit K4. Circuit K4 connects to cavity 4 of the PCM connector.
