Mass Air Flow (MAF) Sensor: Getting The Correct Amount Of Air

“Choose Your Mass Air Flow Help Topic Below”



A (MAF) sensor measures the amount of air entering the engine. And sends this data to the car’s computer (ECU). The (ECU) uses this information to calculate the correct amount of fuel to inject for the optimal air fuel ratio. Which is crucial for engine performance, fuel economy, and emissions control. It is a critical part of a modern fuel injected engines system. Typically located between the air filter and the intake manifold.

So, How Does It Work:

Measures air flow: The sensor uses a hot wire or film that cools down as air passes over it.
Calculates air density: The amount of cooling is directly related to the mass of the air flowing in.
Sends a signal to the (ECU): The sensor converts this measurement into an electrical signal, that the engine’s computer interprets.
Adjusts fuel injection: The (ECU) uses the signal to precisely adjust the amount of fuel to be injected. Ensuring the correct air-fuel mixture for combustion.
Adapts to conditions: Some sensors also include an air temperature sensor. Which helps the (ECU) account for changes in air density due to temperature and altitude.
