Crankshaft Position Sensor: Testing and Inspection

^ The scan tool scan tool displays crankshaft position sensor data as engine speed (RPM). An error in the crankshaft position sensor circuit should set a DTC P0336, P0337, P0338, or a P0339. The crankshaft position sensor provides a signal through the ignition control module which the VCM uses as reference to calculate RPM and crankshaft position.

^ Refer to DTC P0336 CKP Sensor Circuit Performance or DTC P0337 CKP Sensor Circuit Low Frequency or DTC P0338 CKP Sensor Circuit High Frequency or DTC P0339 CKP Sensor Circuit Intermittent. Testing and Inspection
