Camshaft Position (CMP) Sensor
The
Camshaft Position Sensor (CMP) is used to indicate camshaft position so that the Powertrain Control Module
(PCM) can fuel the engine sequentially and determine which cylinder is misfiring when misfire is present. If the PCM receives an intermittent signal from the CMP, then the CMP resync counter will increment. In order to set a DTC, the PCM must see a minimum number of resync's within a maximum time.
