EXHAUST GAS TEMPERATURE SENSOR [SKYACTIV-D 1.5]

id0140z5256600

Exhaust Gas Temperature Sensor No.1

Purpose/Function

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

Construction

•  Installed in the variable geometry turbocharger.

•  A thermistor has been adopted (as the detecting element) for detecting the exhaust gas temperature.

Operation

•  Sends the signal, which fluctuates according to the exhaust gas temperature before it passes through the variable geometry turbocharger, to the PCM.
