Fuel Temperature Sensor (THL) 5) ‡ The fuel temperature sensor detects the fuel temperature and outputs it to the ECU. The sensor uses a thermistor, which varies resistance according to temperature. ‡ As the ECU applies voltage to the thermistor, it uses a voltage resulting from the division of the computer internal resis- tance and the thermistor resistance to detect the temperature. )'9 :8,0 : :
