Crankshaft Position Sensor: Description and Operation

2006 Chevrolet Tahoe 2WD V8-5.3L VIN TSECTION Description and Operation


CRANKSHAFT POSITION (CKP) SENSOR

The crankshaft position (CKP) sensor is a three wire sensor based on the magneto resistive principle. A magneto resistive sensor uses two magnetic pickups between a permanent magnet. As an element such as a reluctor wheel passes the magnets the resulting change in the magnetic field is used by the sensor electronics to produce a digital output pulse. The PCM supplies a 12-volt, low reference, and signal circuit to the CKP sensor. The sensor returns a digital ON/OFF pulse 24 times per crankshaft revolution.
