A mass (air) flow sensor (MAF) is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density with temperature and pressure. In automotive applications, air density varies wi… WebNov 8, 2024 · Usually located in the area between the air filter and the throttle body, the MAF sensor helps the car computer to control engine performance. The signs that it has failed include misfires or the car stalling. Test this sensor using these steps. Step 1. Locate the sensor in the vehicle’s air intake duct.
