P0017 Saab DescriptionThe Camshaft Position (CMP) actuator system enables the Engine Control Module (ECM) to change the timing of the camshafts while the engine is operating. The CMP actuator solenoid signal from the ECM is pulse width modulated (PWM). The ECM control the CMP actuator solenoid duty cycle by controlling the amount of solenoid IN time. The CMP actuator solenoid controls the advance or retard of each camshaft. The CMP actuator solenoid control the oil flow that applies the pressure to advance or retard the camshafts.4
Ignition voltage is supplied directly to the CMP actuator solenoid. The ECM control the solenoid by grounding the control circuit with a solid state device called a driver. Th ECM compares the camshaft position or the camshaft angle, to the position of the crankshaft. If the ECM detects a deviation between the camshaft position target and the crankshaft position, the code will set.
