Camshaft Position Sensor: Description and Operation
Description
Notice: Numbers in text correspond to numbered components in image.
The Camshaft Position (CMP) sensor (1) 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 sensor, then the
CMP Resync Counter will increment. In order to set a DTC, the PCM must see a minimum number of resyncs within a maximum time.
Circuit Faults
A fault in the CMP sensor circuits will cause a DTC P0341 or P0342.
