I've run it through the tests on the Tech II a couple of times and tested the solenoid. It always passes but I agree I should pull the solenoid and check it out. I'll let you know. Thanks for the suggests.
It's one thing to do a sweep test on the Tech 2 but after that if you don't find anything definitive, then you should pull the VPS and check it on the Tech 2 while pushing the plunger in with your finger. You'll want to be looking for it sticking, non-linear vane % or excessive wear at the tip. If it sticks, then I would try cleaning it with brake cleaner and then use a little WD40 after to make sure it slides well and then reinstall. Check again for codes and if it returns I would try replacing the VPS as a first step for that code.
