DTC Description: Notes
WARNING: This page is about a different car, the 2018 Nissan Titan XD. However, it is still accessible from the selected car via links, so may be relevant.
The engine control module (ECM) provides a 5V supply to the camshaft position sensor on the sensor supply circuit. The ECM also provides a ground on the sensor return circuit. As slots in the front of the camshaft gear move past the position sensor, a signal is generated on the signal circuit. The ECM uses this signal to determine engine speed and position. Offset spacing of the cam gear slots indicate to the ECM the position of the engine. This sensor is used as a backup sensor if the engine crankshaft position signal is lost.
