============================
Mass Air Flow Meter (MAF)
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 no start condition, engine surging
