Fuel Tank Temperature Sensor (CNG): Description and Operation

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, 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)
