INTAKE AIR TEMPERATURE (IAT) SENSOR [SKYACTIV-D 1.8]

id0140s1007100

IAT Sensor No.1

Purpose/Function

•  Detects the IAT before it passes through the air cleaner as basic information for mainly determining the fuel injection amount.

•  Detects the IAT before it passes through the air cleaner and sends it to the PCM as an IAT signal.

Construction

•  Built into the MAF sensor.

•  A thermistor has been adopted (as the detecting element) for detecting the IAT.

Operation

•  Sends the signal, which fluctuates according to the IAT (after passing through the air cleaner), to the PCM.
