Engine Fuel Temperature Sensor

Engine Fuel Temperature (EFT) sensor inputs fuel temperature of fuel near fuel injectors to the PCM. EFT sensor is a thermistor device which changes resistance proportionate to temperature changes. Resistance increases as fuel temperature decreases and decreases as fuel temperature increases. Signal is used by PCM to adjust fuel injector pulse width and meter fuel to each cylinder.
