Used Air Flow Meter/Sensor

Used Air Flow Meter/Sensor for sale.

A Mass Air Flow Meter/Sensor (MAF) is one of the key components of an electronic fuel injection system in your car. It is installed between the air filter and the intake manifold of the engine. The mass air flow sensor measures the amount of air entering the engine or the air flow. In modern cars, an intake air temperature sensor or IAT is built in the mass air flow sensor. There are few types of air flow sensors, however, modern cars use a hot-wire type.


Air flow Meter/Sensor problems

Problems with mass airflow sensors are common in many cars, including BMW, GM, Volkswagen, Mazda, Toyota, Nissan, and other brands. The sensor element could get contaminated or damaged.

For example, in some Mazda Skyactiv engines, a failed mass airflow sensor could cause the engine to crank but not to start.

An improperly installed or collapsed air filter can cause the airflow sensor to fail sooner. Over-soaking a washable air filter can also cause trouble with the airflow sensor.
