Circuit/System Description
The camshaft position actuator system enables the Engine Control Module (ECM) to change the timing of the camshafts while the engine is
operating. The Camshaft Position Actuator Solenoid Valve signal from the ECM is pulse width modulated (PWM). The ECM controls the
Camshaft Position Actuator Solenoid Valve duty cycle by controlling the amount of solenoid valve ON time. The Camshaft Position Actuator
Solenoid Valve controls the advance or the retard of each camshaft. The Camshaft Position Actuator Solenoid Valve controls the oil flow that
applies the pressure to advance or retard the camshafts.
