I would start with some research and study up on how the system works.
Things like:
What RPM is the actuator supposed to kick in and out at.
How is the Solenoid is wired? How many wires to the Solenoid? What voltages are spec?
Things like that.
Then I would get some diagnostic equipment like a Durametric or Foxwell scanner so I could look at live data.
Then I could look at things like:
Is the system functioning at all?
Is the solenoid getting voltage?
Are the cams moving at all?
Do I have an open or short in the solenoid wiring harness?
So what you want to start with is a detailed and complete as possible diagnosis of the problem before you start changing out expensive parts.
Isolate and Identify the problem before you fix it.
It could be something as simple as a bad wiring connection.
Or something more complex.
