Air Flow Meter/Sensor: Description and Operation
1986 Ford Aerostar V6-183 3.0LSECTION Description and Operation
The Vane Air Flow Meter, (Figure 1), measures air flowing into the engine and is mounted between the air cleaner and the air throttle body assembly. The meter contains a movable vane directly connected to an electrical device known as a potentiometer. Air, rushing through the vane air flow meter, changes the position of the vane and the potentiometer. The potentiometer relays vane position information to the EEC IV module. The EEC IV module can then translate vane position information into the amount of air flowing into the engine.
Inside the vane air flow meter is an air temperature sensor. This sensor constantly monitors the temperature of the air flowing into the engine. This information is also transmitted to the EEC IV module.
the EEC IV module computes air flow and air temperature information, then adjusts the fuel flow to obtain the optimum air/fuel mixture.
