Put a stop to engine hiccups and stabilize your engines air-fuel mixture with a new mass air flow sensor MAF from AutoZone.

The air flow sensor is located directly in the intake air stream between the air cleaner and. Try to imagine 9000-10000 gallons of air flowing through your engine for every 1 gallon of gas burned. The MAF is typically mounted between the air filter and throttle body.

We carry great brands like ACDelco Bosch Duralast Hitachi and more. Up to 8 cash back Since the function of an MAF is to measure all the air flowing into the engine they have a LOT of air flowing through them. It is located between the air filter and the engines intake manifold.

How the mass air flow sensor is tested In modern cars the only way to test the mass air flow sensor is with a scan. Here mass means quantity as its name defines a mass air flow sensor means a sensor that measures the Quantity Of Air flowing to the engine and then converts it into a voltage value. The ECM needs to know intake air volume to calculate engine load.

Ad Find Deals on mass airflow in Car Parts on Amazon. The Mass Air Flow sensor MAF is one of the key components of an electronic fuel injection system in your car. Some mass flow instruments output a true mass flow measurement directly such as Coriolis instruments.

However there are various types of air flow sensors and all require different maintenance. Youll notice if the tailpipes eject black smoke or when the engine runs rough or backfires. The job of the mass air flow sensor is to keep track of the amount of air coming in through the air filter so that the ECU can adjust the amount of fuel getting into the engine.

True mass flow mass flow rategas density at STP or NTP. By using this flow meter we can determine the mass of the substance that travels through the surface per unit time. Replace The Bad Mass Air Flow Sensor On Your Audi Tt 225Hp With Engine Code Amu.

That much air carries a lot of fine dust and particulates of all types. In some cars the intake air temperature IAT sensor is built into the mass air flow sensor. The mass air flow sensor measures the air mass flowing into the engine intake.

Thermal dispersion flow meters use heat to measure the flow rate of a fluid.
