Camshaft Position Sensor: Description and Operation

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

The PCM receives the camshaft position sensor signal on circuit K24. Circuit K24 connects to cavity A18 of the PCM.

The PCM provides a ground for the camshaft position sensor signal (circuit K24) through circuit K4. Circuit K4 connects to cavity A4 of the PCM.
