BOOST AIR TEMPERATURE SENSOR [SKYACTIV-D 2.2]

id0140z7256400

Purpose/Function

• Detects the IAT after it passes through the charge air cooler as basic information for mainly determining the fuel injection amount.

• Detects the IAT after it passes through the charge air cooler and sends it to the PCM as an intake air temperature signal.

Construction

• Installed on the charge air cooler.

• 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 charge air cooler, to the PCM.
