Ford Fiesta Mass Air Flow Sensor (MAF), 2013–2018, OEM 8V2112B579AA

Mass Air Flow Sensor (MAF), part number 8V2112B579AA, is part of the intake and engine management systems on the Ford Fiesta. The sensor measures the airflow through the intake duct and sends the data to the ECU, which calculates the amount of fuel to inject and helps ensure appropriate combustion.

Over time, the sensor may collect dust or become contaminated, or its sensing element or internal circuitry may fail. If the intake airflow signal is inaccurate, the engine may run unevenly, accelerate poorly, or use an unusual amount of fuel.

This is an OEM product listed for 2013–2018 Ford Fiesta models, according to the product information. Before replacement, check the part number, engine version, and connector to ensure compatibility.
