Thanks for the update, Dave.
The failsafe value for the IAT is 95F. With it unplugged that is the temperature programmed as a substitute input.
Since you do not report DTC 1-1 or 1-2 or 2-1 and since MAP failsafe is normal operation, it is not likely a MAP issue, per FSM pages 5-15 and 5-16...not that I want to discourage checking as many electrical connections as practical.
Be interesting to see inside, as far as possible, with IACV removed.
In the photo posted by Max, the port looks rather large, so I wonder how it could be blocked/partially blocked. Wonder if it is practical to run a pipe cleaner or = to the side?
