Signs that You Have a Failing Mass Air Flow Sensor

The mass air flow sensor (MAF) is a critical component in your car’s fuel injection system. It sits nicely between the air filter and the intake manifold, carefully measuring the amount of air that’s being drawn into the engine to drive the combustion. The sensor sends the information to the Engine Control Unit (ECU), which in turn delivers the correct amount of fuel to the engine. As the sensor picks up different information about air density, temperature and other variables, it ensures that the engine functions at the most efficient level.

Replacing a Mass Airflow Sensor

Mass airflow sensor

Your car’s mass airflow sensor is the part of the engine that’s used to monitor the amount of air used in the combustion process. The part is only found on fuel-injected engines and it works with the ECU to ensure that the right amount of air is being supplied to the engine, to ensure efficient combustion of fuel in the cylinders.
