Hi all. I have a seat Ibiza 1.2 3 cylinder engine ( aqz ) e/m light on and dtc stored as MAP sensor implausible signal. However I have vacuum tested the man pressure and its ok. There are no air leaks and no restrictions in the exhaust system.I have spoke to a dealer tech and he says the throttle body's are common to cause this fault.Has anybody come across this b4? By the way fuel trim is constant -20% But not sure if this is because in limp mode.
