Air Flow Meter/Sensor: Specifications

Mass air flow (MAF) sensor
The mass airflow sensor gives engine control module (ECM) information about the air mass that passes through the sensor, which then is sent into the engine as well as the temperature of that air.

The values should be regarded as approximate.
