Purpose, Function
Conducts fresh air from outside the engine compartment.
Increases air density by taking fresh air, which is cooler than the engine compartment, to enhance the charging efficiency, ensuring the combustion stability.
Construction
The fresh-air duct is installed to the air cleaner.

Purpose, Function
The switch turns on/off in conjunction with the rotation of the latch lever,
and it detects the open/closed condition of the liftgate by the voltage value
which is changed by the rear body control module (RBCM).

Intake Air Temperature (Iat) Sensor Inspection
IAT Sensor No.1
Resistance inspection
NOTE:
Because the IAT sensor No.1 is integrated in the MAF sensor, replacing the
IAT sensor No.1 includes replacement of the MAF sensor/IAT sensor No.1.
1. Disconnect the negative battery cable..
2. Disconnect the MAF sensor/IAT sensor No.1 ...
Oil Pump [Skyactiv G 2.0]
Outline
The oil pump has a mechanism for feedback control of oil pressure. As a result,
an oil pressure increase of more than the set pressure is suppressed and oil
pump drive resistance is reduced. In addition, because the set pressure can
be changed (oil pressure two-step control) ...
