About MAF:
A mass air flow sensor, also known as a mass air flow meter, is one of the important sensors of an EFI engine. It converts the intake air flow into an electrical signal and sends it to the electronic control unit (ECU). Mass Air Flow Sensor, it’s more commonly known as a MAF sensor, air meter or sometimes simply MAF. While it might have many names, it’s responsible for just one, but still very important job: measuring the amount of air entering the engine.
The mass air flow sensor installation location is as follows:
(1) Between the air filter and the throttle body.
(2) On the air cleaner.
(3) On the engine.
How does a MAF sensor work?
Installed in the intake pipe between the air filter housing and the intake manifold, most MAF sensors work on the hot wire principle. Put simply, a MAF has two sensing wires. One is heated by an electrical current, the other is not. As air flows across the heated wire, it cools down. When the temperature difference between the two sensing wires changes, the MAF sensor automatically increases or decreases the current to the heated wire to compensate. The current is then changed to a frequency or a voltage that is sent to the ECU and interpreted as air flow. The quantity of air entering the engine is adjusted accordingly.
What to look out for in a failing MAF sensor?
- Check engine light: as with most engine management components, a problem with the MAF sensor often causes the check engine light to come on.
- Engine runs rich at idle or lean under load: this would typically point towards a contaminated hot wire.
- Engine runs rich or lean: caused by the MAF continuously misreporting airflow into the engine – a diagnostic procedure will be required to confirm this.
- Rough idle or stalls: a failed MAF sensor will not send any airflow information to the ECU preventing it from accurately controlling fuel.
- Excessive vibrations when stationary.
- RPMs changing noticeably without driver input.
