What Does a Mass Air flow Sensor Do? Your mass air flow sensor or âMAFâ detects the volume of air as it enters your engine by heating up a thin wire or resistor. The computer in your car then measures electrical resistance through the MAF as the air flowing through the sensor cools its components down. With a firm understanding of how much air is flowing into your engine, the computer can then direct fuel injectors to add more or less gasoline to the air/fuel mixture.
The mass air flow (MAF) sensor measures the mass of the air entering the engine. Because air mass varies with air temperature (cold air is denser than warm air), measuring air mass provides the PCM with a very acurate way of determining the correct amount of fuel to obtain the ideal fuel/air mixture.fter you clean the mass air flow sensor make sure to reset the check engine light. You can reset your check engine by going to Auto Zone or Kragen Auto Parts and ask to borrow the code reader* (it's free all you need is your ID and credit card) to check out the code reader.
