OEM Mass Air Flow Sensor (MAF) for Ford Ranger & Everest 2015–2020, 8V2Z12B579A

Mass Air Flow Sensor (MAF), part number 8V2Z12B579A is part of the vehicle’s air intake and engine management systems. The sensor measures the airflow through the intake duct and sends a signal to the ECU, which calculates the appropriate amount of fuel to inject for the operating conditions.

If the sensor does not operate accurately or is damaged, the data sent to the ECU may be incorrect, causing the engine to run unevenly, accelerate poorly, or use more fuel. Accumulated dirt, oil, and moisture can also affect sensor accuracy.

This is an OEM product listed for 2015–2020 Ford Ranger and Ford Everest models. Before replacement, check the correct part number, engine, and vehicle electrical system configuration.
