Circuit Description
WARNING: This page is about a different variant/trim than selected.
The camshaft position (CMP) actuator system is comprised of 4 CMP actuator solenoids, 4 oil control valves, and 4 CMP actuators. The engine control module (ECM) sends an electrical signal through the control circuits to the CMP actuator solenoids when a cam timing change is desired. The ground circuits of the CMP actuator solenoids are used as a return. If the ECM detects incorrect voltage on one of these circuits, DTC P0010, P0013, P0020, P0023 sets.
