Mass Air Flow (MAF) Sensors
The mass air flow sensors converts the amount of air drawn into the engine into a voltage signal.The ECM needs to know intake air volume to calculate engine load. This is necessary to determine how much fuel to inject,when to ignite the cylinder, and when to shift the transmission.The air flow sensor is located directly in the intake air stream,between the air cleaner and throttle body where it can measure incoming air.

There are different types of Mass Air Flow sensors.The vane air flow meter and Karmen vortex are two older styles of air flow sensors and they can be identified by their shape.The newer, and more common is the Mass Air Flow (MAF) Sensor.
