Mass Airflow Sensor

A mass air flow sensor (MAF) is a detector that measures the amount of air that enters the engine. This part is positioned between the air filter and intake manifold within the engine. Once the sensor measures the amount of air, this information is sent to the engine control module. This determines the amount of fuel injection needed that creates a balanced air-fuel ratio. The oxygen sensor works to make sure the air flow is the correct amount detected by the MAF.

Hot wire devices are the most common type used today; a temperature sensor is placed near the mass flow sensor to detect the heat being produced. If the air and fuel mixture is off, the check engine light could come on. Some other issues seen are: irregular idling, engine shutting off, pauses when you speed up, and fewer miles per gallon.
