Sensor, Camshaft Position: Description
The Camshaft Position (CMP) sensor (1) is mounted to the cylinder head. The hall effect sensor generates a signal that corresponds to the camshaft position of rotation. The Powertrain Control Module (PCM) uses the CMP sensor signal to detect the Top Dead Center (TDC) position of cylinder 1. The PCM controls injection timing and the duration of time each injector delivers fuel during an injection cycle based on the CMP sensor signal and the Crankshaft Position Sensor (CKP) sensor signal.
