Hello, is that a P0010 and P0011 I assume? With both of these codes together it points to the Camshaft Position (CMP) Intake Actuator Solenoid Valve. Is this a 2.8L or 2.0 with a Turbo?

There is a TSB on the camshaft actuator solenoids breaking an internal wire. You should be able to monitor the Intake Camshafts "Desired Position" vs its "Actual Position" on your scan tools live data. With the code set it will be most likely (supposed to be) in its locked position, so there shouldn't be any advance on the intake cam at idle or with the code set, you can clear the codes and see if there is any movement until it sets the code again. At higher rpm is where you would see intake cam advancement. But if the solenoid is faulty, you won't see any movement. Or shouldn't. If its intake cam timing is jumping around it is possible the lock pin inside the actuator is broken. But check the solenoid first. If it's an open circuit inside on a resistance check (unplugged), then it just needs to be replaced, the cam actuator itself is another story, it looks like the actuator is attached to the camshaft and service info shows the entire camshaft being removed. So hopefully it is just the solenoid.

Yeah, the intake cam is a 6.6-hour job alone. If the phaser is broken internally.
