I found a site called actron.com that describes OBDII codes.
Autozone explains what the camshaft position sensor is.
Camshaft Position Sensor Actuator
The Camshaft Position (CMP) actuator is attached to each camshaft and
is hydraulically operated in order to change the angle of the camshaft
relative to Crankshaft Position (CKP). The CMP actuator solenoid is
controlled by the control module. The control module sends a pulse
width modulated 12-volt signal to a CMP actuator solenoid. The
solenoid controls the amount of engine oil flow to a CMP actuator. The
CMP actuator can change the camshaft angle a maximum of 25 degrees.
The control module increases the pulse width to accomplish the desired
It then goes into detail on how to remove and reinstall it.
Removal & Installation
Remove the intake manifold cover.
Disconnect the engine wiring harness electrical connector from the exhaust Camshaft Position (CMP) actuator solenoid valve, if required.
Disconnect the engine wiring harness electrical connector from the intake CMP actuator solenoid valve, if required.
Remove the exhaust CMP actuator solenoid valve bolt and valve, if required.
Remove the intake CMP actuator solenoid valve bolt and valve, if required.
Inspect the solenoid valve O-ring seals for damage, replace as necessary.
Installation is the reverse of removal, tighten the bolt to 89 in. lbs. (10 Nm).
Lubricate the solenoid valve O-ring seals with clean engine oil.
