Crankshaft Position Sensor: Description and Operation

Crankshaft Position Sensor:

Crankshaft Position Sensor
The Crankshaft Position (CKP) sensor provides the PCM with crankshaft speed and crankshaft position. The PCM utilizes this information to determine if an engine Misfire is present. The PCM monitors the CKP sensor for momentary drop in crankshaft speed to determine if a misfire is occurring. When the PCM detects a misfire, a DTC P0300 will set.

Circuit Malfunctions
The PCM also monitors the CKP sensor signal circuit for malfunctions. The PCM monitors CKP signal and the low resolution signal. The PCM calculates these signals to determine a degree of deviation. When the PCM detects that the degree of deviation is out of normal operating range, the PCM will set a DTC P0335 or a DTC P0336.
