• The FTS sensor is a two (2) wire thermistor sensor.
• The FTS sensor’s internal thermistor forms a voltage divider with a pullup resistor inside the ECM.
• The FTS sensor changes resistance when exposed to different temperatures.
• When the temperature of the fuel decreases, the resistance of the thermistor increases and the signal voltage increases.
• When the temperature of the fuel increases, the resistance of the thermistor decreases and the signal voltage decreases.
