Exhaust Gas Temperature Sensor

WARNING: This page is about a different car, the 2014 Nissan Pathfinder. 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.
