How difficult to repair Camshaft Position Sensor Actuator?

I got a code POO13 for my Saturn VUE 2008 2.4 liters.  By google search, the solution would be something below.



Camshaft Position Sensor Actuator

Operation

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 camshaft operation.

It then goes into detail on how to remove and reinstall it.

Removal & Installation

2.4L Engine

1. Remove the intake manifold cover.

2. Disconnect the engine wiring harness electrical connector from the exhaust Camshaft Position (CMP) actuator solenoid valve, if required.

3. Disconnect the engine wiring harness electrical connector from the intake CMP actuator solenoid valve, if required.

4. Remove the exhaust CMP actuator solenoid valve bolt and valve, if required.

5. Remove the intake CMP actuator solenoid valve bolt and valve, if required.

6. Inspect the solenoid valve O-ring seals for damage, replace as necessary.

To install:

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.

My question: how difficult to repair it?
Thanks
