Air flow sensor is installed in the air intake hose. Air
flow sensor is composed of an extremely small heat-
sensing resistor. The air flow sensor controls the
amount of electric current flowing into the heat sens-
ing resistor to keep the heat sensing resistor at a

constant temperature to the intake air temperature.
When the air mass flow rate increases, the air flow
speed is higher and also the amount of heat transfer
from the heat sensing resistor to the air increased.
Therefore, the air flow sensor increases the amount
of electric current to the heat sensing resistor. Thus,
the amount of electric current increases in accord-
ance with the air mass flow rate. The air flow sensor
measures the air mass flow rate by detecting the
amount of electric current. The air flow sensor ampli-
fies the detected electric current amount and outputs
it into the engine-ECU. Engine-ECU uses this output
current and engine speed to calculate and decide
basic fuel injection time. Sensor properties are as
shown in the figure.
