Circuit Description

The exhaust camshaft position (CMP) sensor produces a 5X plus a sync signal for each revolution of the exhaust camshaft. These signals are for control of sequential fuel injection and for exhaust camshaft phaser control. The CMP is connected directly to the powertrain control module (PCM) and consists of the following circuits:

• A 12-volt reference circuit
• A low reference circuit
• A CMP sensor signal circuit

If the PCM does not receive 5 CAM pulses within a certain amount of time, DTC P0365 will set.
