Fuel Temperature Sensor
WARNING: This page is about a different car, the 2018 Nissan Titan XD. However, it is still accessible from the selected car via links, so may be relevant.
The fuel temperature sensor measures fuel temperature before it passes through the stage 2 fuel filter housing. This sensor is critical for determining if fuel temperature is within specifications. If fuel temperature is above specifications, a DTC could be set and engine power may be reduced to protect the engine.
