Sorry, on vacation for a few weeks and not where the car is. When Iget back would be happy to check if you haven't rec'd an answer yet.

Still haven't solved my P0200 code, but mine is related to the car not thinking the flap is opening when it really is. I think it is a bad wire coming from the flapper switch that gives tells the CPU that the flap is open. Unfortunately, it will probably require another removal of the intake manifold to address the issue, and since I know the flap is working, and since the car is running great, I have not been too motivated to fix it.
