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 crankshaft position and camshaft position sensors are Hall effect type sensors. The engine control module (ECM) provides a 5V supply and a return circuit to the position sensors. As holes drilled in the flywheel or slots in the front of the camshaft gear move past the position sensor, a signal is generated on the position sensor signal circuit. The ECM uses this signal to determine engine speed. Offset spacing of the drillings or slots indicate to the ECM the position of the engine.
