Fuel Tank Temperature Sensor (CNG)

FUEL TANK TEMPERATURE SENSOR (CNG)






The Fuel Tank Temperature (FTT) sensor is a thermistor mounted on the CNG fuel tank and is used to calculate fuel density. The Compuvalve sends the FTT a five volt reference. The FTT sensor is also used to keep the fuel gauge from fluctuating during temperature changes. A non-functioning sensor will give a constant reading of 15°C (59°F) (F-Series) or 0°C (32°C) (Contour).
