Fig. 43: View Of Advance And Retard Cavities 1. Pressurized oil enters the retard cavities (2) of the actuator and moves the park pin (3) from the locked position. 2. As pressure increases within the retard cavities (2), the rotor and camshaft rotate counter

clockwise retarding valve timing. 3. As the duty cycle decreases, the spool is repositioned and oil is sent to the advance cavities (1), rotating the rotor and camshaft clockwise, advancing valve timing. With a 0 percent duty cycle signal to the magnet, the spool is positioned in the fully With a 50 percent duty cycle, the spool is positioned neutral, with no flow to either the With a 51-100 percent duty cycle, the spool is positioned to provide oil flow to retard With a 100 percent duty cycle, there is full flow to the retard cavities of the actuator. The above duty cycle percentage values are only a guideline, as the actual duty cycle CMP Actuator Park Position Verification
