Briefly, A Mass airflow sensor is a device used by the engine control computer to measure the amount of air entering the engine through its air intake system.

I pulled this from your Service Manual Section EC - ENGINE CONTROL SYSTEM...

MASS AIR FLOW SENSOR

The mass air flow sensor is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake flow. It consists of a hot film that is supplied with electric current from the ECM. The temperature of the hot film is controlled by the ECM a certain amount. The heat generated by the hot film is reduced as the intake air flows around it. The more air, the greater the heat loss.

Therefore, the ECM must supply more electric current to maintain the temperature of the hot film as air flow increases. The ECM detects the air flow by means of this current change.
