Description



The mass air flow sensor (1) is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake flow.



The mass air flow sensor controls the temperature of the hot wire to a certain amount. The heat generated by the hot wire is reduced as the intake



air flows around it. The greater air flow, the greater the heat loss.



Therefore, the electric current supplied to hot wire is changed to maintain the temperature of the hot wire as air flow increases. The
