Air Flow Meter/Sensor: Description and Operation
The vane air flow meter measures air flowing into the engine and is mounted between the air cleaner and the throttle body assembly. The meter
contains a movable vane directly connected to a potentiometer. Air rushing through the vane air flow meter, changes the position of the vane and
potentiometer. The potentiometer relays vane position information to the EEC-IV module. The EEC-IV module, translates vane position information into
the amount of air flowing into the engine.
An air temperature sensor is incorporated within the engine and also transmits the information to the EEC-IV module. The EEC-IV module receives,
then computes the air flow and air temperature information and adjusts the fuel flow to obtain the optimum air/fuel mixture required.
