Engine Oil Temperature Sensor
WARNING: This page is about a different car, the 2018 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.
The engine oil temperature sensor is used to detect the engine oil temperature. The sensor modifies a voltage signal from the ECM. The modified signal returns to the ECM as the engine oil temperature input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases.
