CMP Actuator Solenoid Circuit Diagnostics

The powertrain control module (PCM) monitors the control circuits of the camshaft position (CMP) actuator solenoid for electrical faults. The PCM has the ability to determine if a control circuit is open, shorted high and shorted low. If the PCM detects a fault with a CMP actuator solenoid circuit a diagnostic trouble code (DTC) will set.
