P0014 HUMMER Meaning

The Camshaft Position (CMP) actuator is attached to each camshaft and is hydraulically operated in order to change the angle of the camshaft relative to Crankshaft Position (CKP). The CMP actuator solenoid is controlled by the control module. The control module sends a pulse width modulated 12-volt signal to a CMP actuator solenoid. The solenoid controls the amount of engine oil flow to a CMP actuator. The CMP actuator can change the camshaft angle a maximum of 25 degrees. The control module increases the pulse width to accomplish the desired camshaft operation.
