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.^ DTC P0336 CKP Sensor Circuit Performance
^ DTC P0337 CKP Sensor Circuit Low Frequency
^ DTC P0338 CKP Sensor Circuit High Frequency
^ DTC P0339 CKP Sensor Circuit Intermittent.
For the above DTC's Refer to Diagnostic Tables / Diagnostic Trouble Code Tables. Testing and Inspection
