[QUOTE="jarance, post: 123228, member: 21"] Oops.. you are right about it.. Fab, thanks for pointing out the error.. Come to think about it, the air flow is determined by the degree of deflection of the vane. When more air is being drawn into the trottle body, the more the vane have to open. This deflection is being monitored via a resistor printed circuit board. By measuring the change in the resistance, you can basically determined the air flow.. I think air flow is equivalent to the square root of the resistance change.. fab.. please confirm the above.. hate to be wrong twice in a row.. :eek: Here is a pic of how the AFM works!! (borrow somebody pic) ___________________________________________________ [IMG]http://i122.photobucket.com/albums/o271/pbjy/AFM/afm_in.jpg[/IMG] ___________________________________________________ [/QUOTE]
