INTAKE AIR TEMPERATURE (IAT) SENSOR [SKYACTIV-D 2.2]

id0140z7007100

IAT Sensor No.1

Purpose/Function

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

•  Detects the intake air temperature before it passes through the air cleaner and inputs it to the PCM as an intake air temperature signal.

Construction

•  Built into the MAF sensor.

ac5wzn00001623

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

Operation

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

IAT Sensor No.2

Purpose/Function

•  Detects the IAT (in intake manifold) as basic information for mainly determining the fuel injection amount.

•  Detects the IAT (in intake manifold) and inputs it to the PCM as an intake air temperature signal.

Construction

•  Installed on the intake manifold.
