Will a bad donut in the exhaust affect the map sensor?

If something blocks the exhaust, it can effect vacuum. Check the sensor circuits, also vacuum.

Something organic like a donut will burn up and be expelled rather quickly, run a scan and check for unresolved fault codes, as JDL says a vacuum leak will affect a MAP sensor as well.
