(easy question) MAP sensor check valve
The S5 Turbo MAP (pressure) sensor isn't supposed to have a check valve in the vacuum line, is it? Doesn't look like it in the FSM, but I could hardly get a clear picture on the internet.
My ECU isn't seeing a vacuum signal on the Palm, and it holds a boost signal after the BOV closes. There is a check valve installed on the vac line from when PO did the swap I believe, and neglected to take it off.

Now I'm fighting an overheating issue... and I used to think I was the pro at overheating issues. Just replaced the thermostat with an Autozone one - it even had the damned jiggle pin in it, I'm going to see if Mazda has one locally, but I have little faith. I replaced the water pump a few weeks ago - I thought I saw a dried trail of coolant from the weep hole, this was before the overheating.
I've been scratching my head over whether or not there's a bubble in one of the lines somewhere, but I've pulled and pinched and no luck. Who knows...
