Caution: Do not push or pull on the reluctor wheel of the camshaft position (CMP) actuator during removal or installation. The reluctor
wheel is retained to the front of the CMP actuator by 3 roll pins. Pushing or pulling on the wheel may dislodge the wheel from the front
of the actuator. The actuator return spring is under tension and may rotate the dislodged reluctor wheel, causing personal injury.
7. Loosen and separate the CMP actuator and timing chain from the camshaft. Position your fingers behind the actuator sprocket and pull the actuator
away from the front of the camshaft. Never pull on the reluctor wheel when attempting to remove the actuator.
8. Insert and secure a tie strap (1) through the center of the actuator and over the reluctor wheel.
9. Remove the timing chain tension bolts (231) and tensioner (232).
