EXHAUST GAS TEMPERATURE SENSOR [SKYACTIV-D 2.2]

id0140z7256600

Exhaust Gas Temperature Sensor No.1

Purpose/Function

•  Detects the exhaust gas temperature before it passes through the turbocharger as basic information for mainly determining the fuel injection amount, EGR control, and boost control.

•  Detects the exhaust gas temperature before it passes through the turbocharger and sends it to the PCM as an exhaust gas temperature signal.

Construction

•  Installed on the turbocharger.

Fuel injector (2pin type)
