INTAKE AIR TEMPERATURE (IAT) SENSOR [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (E))]

id0140u1007100

IAT Sensor No.1

Purpose/Function

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

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

Construction

•  Built into the MAF sensor.

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

Operation

•  Sends a signal to the PCM via SENT communication which fluctuates according to the intake airflow amount just after it passes through the air cleaner.

IAT Sensor No.2

Purpose/Function

•  Detects the IAT (in intake manifold) after it passes through the throttle body as basic information for mainly determining the fuel injection amount.

•  Detects the IAT (in intake manifold) after it passes through the throttle body and sends it to the PCM as an IAT signal.

Construction

•  Built into the MAP sensor.
