Fuel Temperature

RANGE -28°C to 140°C, -18°F to 285°F:
There is a thermistor located in the optical sensor that determines fuel temperature. When the sensor is cold and the internal resistance is high, the PCM monitors a high signal voltage, which it interprets as low fuel temperature. As the sensor warms and the internal resistance is low, the voltage signal will decrease and the PCM will interpret the low voltage as warm fuel.
