Mass Air flow Sensor (MAF): how it works, symptoms ...

+

· The Mass Air Flow sensor (MAF) is one of the key components of an electronic fuel injection system in your car. It is installed between the air filter and the intake manifold of the engine. See the diagram. The mass air flow sensor measures the amount of air entering the engine or the air flow. In modern cars, an intake air temperature or IAT ...

The air is then mixed with the fuel, and combustion is the result. This is what propels the car. There is a sensor on the air intake called the mass air flow sensor. This sensor calculates how much air to mix with the fuel. If you are using a cold air intake, the MAF sensor might not be calculating properly.

· MAF = Mass Air Flow and is a sensor that measures the actual air flow going into the engine. The one above heats a wire and then measures how much the airflow cools it off so it can determine the air flow. While the one below just measures how much the airflow opens the door. Actual air flow (MAF) is more accurate than calculated air flow.

· In one design called a hot wire mass flow sensor, an electrical current is fed to a resistive wire which is in proximity to temperature sensors. As the air flow passing through the sensor increases, convective heat transfer causes a temperature drop in the wire, reducing its electrical resistance.

Mass Air Flow Sensors vs Manifold Air Pressure Sensors ...

MAF is an acronym for "mass air flow." Unlike IAT sensors, MAF sensors measure air volume with temperature at once. Remember, the MAP sensor above measured intake manifold pressure / vacuum and then estimated air volume with computer software. An MAF actually measures real air volume so that the computer doesn''t need to guess what it might be.
