CMP Actuator Solenoid Circuit Diagnostics
WARNING: This page is about a different car, the 2007 Isuzu i-370, 2007 GMC Canyon, and 2007 Chevrolet Colorado. However, it is still accessible from the selected car via links, so may be relevant.
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 DTC will set.
