Fuel Tank Temperature Sensors

The fuel tank temperature sensors:

• change resistance in response to the temperature of the fuel in the fuel tank; as the surrounding temperature increases, the resistance decreases (the voltage signal also decreases).
• provides a signal to the NGV module that indicates the temperature of the fuel.
• are located next to the fuel tanks (9002), one in the vent box at Fuel Tank No. 1 (Fuel Tank Temperature Sensor No. 1) and one below the vehicle at Fuel Tank No. 4 (Fuel Tank Temperature Sensor No. 2).
