Intake Air Temperature Sensor: Description and Operation
Intake Air Temperature Sensor Circuit
The Air Temperature Sensor (Intake), located on the Air Flow Sensor (AFS), is a resistor-based sensor for detecting the intake air temperature. The ECU
provides necessary fuel injection control according to the intake air temperature signal, from this sensor. The resistance of the sensor increases as
temperature decreases.
