Mass Air Flow Meter (MAF)
Location: 
The Mass Air Flow (MAF) sensor is located in the air duct between the air cleaner 
and the engines air intake. Location may be mounted to the throttle body or in the air cleaner 
housing.
The MASS Air Flow sensor is a computer input that measures the amount of 
air entering the engine. Barometric pressure may also be calculated either in the sensor or by 
the computer for correct air/fuel mixture. The computer uses this information for air/fuel 
mixture control, ignition timing and to aid the transmission in pressure control for accurate 
shifting. 
Failure Symptoms: Malfunction Indicator Light illumination, failed emission test, 
engine hesitation on acceleration, poor fuel economy, poor engine performance, engine nostart condition, engine surging.
