Fuel Temperature Sensor(FTS) is negative temperature characteristic thermistor installed in fuel supplying line. It senses the termperature of fuel supplied to high pressure pump. Fuel temperature is limmited to protect fuel such as high pressure pump and injectors from damages due to rapid deterioration by vapor-lock which can occur at high temperature or destruction of oil membrance.

Turn the ignition key off.
Disconnect Fuel Temperature Sensor connector.
Measure resistance between the terminals 1 and 2 of FTS connector.
Refering to "SPECIFICATION", check that the resistance is within specification.
