Intake Air Temperature Sensor: Description and Operation
Located on the air cleaner outlet hose, this sensor constantly measures the temperature of the air entering there and converts a change in the air
temperature into that in resistance through its thermistor. That is, as air temperature lowers, resistance increases and as it rises, resistance decreases. As
air density of the intake air varies with variation in temperature, ECM, by monitoring the resistance, adjusts the amount of fuel injection according to the
air temperature.
