Code P0017 Buick Description

The Camshaft Position (CMP) actuator system is controlled by the control module. The Engine Control Module (ECM) sends a pulse width modulated signal to a CMP actuator solenoid in order to control the amount of engine oil flow to a camshaft actuator passage. There are 2 different passages for oil to flow through, a passage for CAM advance and a passage for CAM retard. The camshaft actuator is attached to the front of the camshaft and is hydraulically operated in order to change the angle of the camshaft relative to the Crankshaft Position (CKP). Engine Oil Pressure (EOP), viscosity, temperature, engine oil level, and aftermarket engine oil additives can have an adverse effect on camshaft phaser performance. The Diagnostic Trouble Code (DTC) will be set when the ECM compares the signals of the crankshaft position sensor and both camshaft position sensors to detect if the signals are out of sync.
