It would seem to me that the CPS and VVT are working in tandem...replace one and you should also replace the other. Just looking for some clarification....Thanx

The Cam Position Sensor only tells the ecu where the cam is compared to the crank. The computer changes the duty cycle of VVT actuator to hit the commanded cam angle. The computer has limits on how far it can change duty cycle to hit the target.
Your problem could be the actuator, sensor, phaser, or out of timing.
