Sometimes it is slow to react, taking several seconds to get to 23 degrees. Sometimes when it returns to idle, it remains at 23 degrees, idles like crap, and throws the CEL.
So, this is the solenoid going out, correct? Why in the heck are these $600?
Bank 1 is cylinders 1-3, right? I assume that's driver's side?
How much of a PITA are these to replace?

A solenoid is an electromagnetic device. Works like a plunger.
It moves the plunger and exposes oil passages. The oil passages then provide oil pressure to actuate the Variocam actuator, which moves the cam.
Although the solenoid could be reacting slowly.
It is more likely that the oil passages are restricted. They are very small.
Or some other issue. Like the green O-ring seals failing (as mentioned in post #4 this thread).
If your Duratech has a live test feature you can trigger the solenoid.
Take the engine cover off and engine not running. Trigger the solenoid and listen for the solenoid to click. That would at least tell you if the solenoid is responding correctly.
You can also trigger the solenoid with a small battery like a nine volt.
Use the search function: There should be info on replacing the solenoid.
