Exhaust Gas Temperature Sensor
WARNING: This page is about a different car, the 2016 Infiniti QX80. However, it is still accessible from the selected car via links, so may be relevant.
Exhaust gas temperature sensor (EGT sensor) is installed exhaust manifold. Exhaust gas temperature sensor uses a thermistor which is sensitive to the change in temperature. Electrical resistance of the thermistor decreases in response to the temperature rises.
