I just received 2 new sensors, the blue one for the water and the MAP sensor you're talking about. I should receive a new air sensor tomorrow, and will try to fit all of them on wednesday. I will try to compare their value at the same time.
There is probably a leak somewhere, maybe a worn seal. It will be checked when the injectors will be cleaned.
I cleaned the throttle body and didn't use the car much from then on, I doubt it is the culprit. I remember checking the pipe from the MAP too, it was fine.
