RedDrifter Posted May 2, 2006 Share Posted May 2, 2006 Theres an elememnt that heats up and this element is cooled down by the passing air. The more air that flows over it the cooler it gets and the resistance changes of the element. Very accurate way of determining how much air is flowing into the motor.

Busky2k Posted May 2, 2006 Share Posted May 2, 2006 Yep and when they get dirty they can't accurately measure the air or go a bit haywire, especially at low loads.
