Crankshaft Position (CKP) Sensor

The CKP sensor provides a signal to the electronic Ignition Control Module (ICM), which the PCM uses as a reference to calculate RPM and the crankshaft position. A fault in the CKP sensor circuits will cause a DTC P0335.

IMPORTANT: A Crankshaft Position System Variation Learning Procedure must be performed any time a change is made in the relationship of the crankshaft sensor to the crankshaft. Changing the crankshaft sensor to crankshaft relationship without performing this procedure will cause the PCM to be unable to detect misfire at all speeds and loads accurately. When this occurs, a false misfire DTC may be set. Removing a part for inspection and then reinstalling the same part is considered a disturbance. A false DTC P0300 could be set if this procedure is not performed. Refer to the CKP System Variation Learn Procedure for the Crankshaft Position System Variation Learning Procedure.
