Crankshaft Position Sensor Operation

Circuit K7 supplies 8 Volts from the Powertrain Control Module (PCM) to the crankshaft position sensor. The K7 circuit connects to cavity 44 of the PCM connector, and cavity 3 of the crankshaft position sensor.

Circuit K24 from the sensor provides an input signal to the PCM. The K24 circuit connects to cavity 25 of the PCM, and cavity 1 of the crankshaft position sensor.

The PCM provides a ground for the crankshaft position sensor signal (circuit K24) through circuit K4. Circuit K4 connects to cavity 51 of the PCM connector and cavity 2 of the crankshaft position sensor connector.
