Air Flow Meter/Sensor: Description and Operation
MASS AIR FLOW (MAF) SENSOR
The mass air flow (MAF) sensor measures the difference between the volume and the quantity of air that enters the engine. "Volume" means the
size of the space to be filled. "Quantity" means the number of air molecules that will fit into the space. This information is important to the PCM
because heavier, denser air will hold more fuel than lighter, thinner air. The PCM adjusts the air/fuel ratio as needed depending on the MAF value.
The scan tool reads the MAF value and displays it in terms of grams per second (gm/s). At idle, the scan tool should read between 4-7 gm/s on a
fully warmed up engine. Values should change quickly on acceleration. Values should remain stable at any given RPM. A failure in the MAF
sensor or circuit will set DTC P0101, DTC P0102, or DTC P0103.
