7X Crankshaft Position (CKP) Sensor

The ignition control module uses the 7X crankshaft position sensor to generate 3X reference pulses witch the PCM uses to calculate RPM and crankshaft position. The PCM uses the pulses to initiate injector pulses. if the PCM does not receive pulses on this circuit the DTC P1374 will set and the PCM will use the 24X reference signal circuit for fuel and ignition control.
