P112F Manifold Air Pressure ... Bank 1

[schwim]

Hello there, folks


I've got an error on the 2011 3.5i xDrive of P112F MAP to throttle angle too high bank 1. The error will go away for a few days, then return for a few, repeating the cycle indefinitely.



I've done a lot of Googling and have read that I should consider everything from a loose/broken vacuum line to a cracked cylinder head with a shocking number of potential causes in between. What's making the searches more useless is the confidence with which each person states the most likely cause and the confidence of the next person stating it can't possibly be that but most likely "X" instead.



Where should I start? In what order should I try things to pin down the cause? I'm not averse to taking it to a shop but if there's some likely culprits I can take out of the equation, the better off I am.


Thoughts are most welcome. Thanks for your time!

If I see "throttle angle" I check the TPS values real-time. There are two for redundancy and if one is intermittent you can get there symptom you describe.
