Crankshaft Position Sensor-2

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.
