I always test my mafs as a no air flow test (n62) but im not sure the no flow voltage are with the n/e60
That is true, but I still have seen values within the usability range on our motors. Generally most E60's I've had have been at 1.10v at idle. Now if it falls below 1v then ECU might enter into limp mode.
