Mass air flow meter repair

We explain the basics of a mass air flow sensor, also known as airflow meter, and explain how to change the MAF.MAF-shop.A mass air-flow sensor is used on fuel-injected vehicles to tell the computer how much air is going into the engine. Discover why a mass air flow sensor must be removed in order to be checked with help from an auto mechanic in this free video on auto parts.It depends on the type of car you drive and the auto repair shop you go to. Our mechanics are mobile, which means they don't have the overhead that repair shops have. MAF) sensor measures the volume of air entering the engine so the Engine Control Unit (ECU) can calculate how much gasoline the fuel injectors should deliver to each cylinder in order to create the proper fuel-air ratio.

Sometimes, however, a malfunction in this little instrument can lead to big problems, usually resulting in very poor engine performance.

Mass airflow sensor problems can cause a variety of symptoms from the annoying to the must repair. We'll discuss these in-depth on this page.

An Air Flow Meter, AFM or Air Mass Meter, AMM measures the air flow or air mass that is drawn into the intake of the engine. This measurement is transmitted as a frequency or a variable voltage to the ECM, ECU, or PCM so that it can calculate the correct amount of fuel to deliver via the injectors in relation to the air going into the engine. The Benefits of Cleaning Your Mass Air Flow SensorThe more oil and dirt that accumulates on your MAF, the worse it serves its purpose.
