Component Description
The mass air flow sensor (MAFS) is placed in the stream of intake
air. It measures the intake air flow rate by measuring a part of the
entire intake air flow. It consists of a hot wire that is supplied with
electric current from the ECM. The temperature of the hot wire is
controlled by the ECM a certain amount. The heat generated by the
hot wire 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 wire as air flow increases. The ECM
detects the air flow by means of this current change.

Component Description
MASS AIR FLOW SENSOR (MAFS)
The mass air flow sensor measures the intake air flow rate by
monitoring a part of the entire flow. Measurements are made by the
ECM which receives electrical signals from the mass air flow sen-
sor which is proportional to the amount of heat emitted from the hot
wire placed in the stream of the intake air.
When intake air flows into the intake manifold through a route
around the hot wire, the heat generated by the hot wire is carried
away by the air flow. The amount of heat detected depends on the
volume of air flow. The temperature of the hot wire is automatically
controlled to maintain it within a finite range regardless of the air
flow rate by regulating the current supplied to the hot wire.
The ECM monitors the air flow by means of the corresponding
electric change.
