FLEX FUEL SENSOR

M FF-395 Flex Fuel sensor reports the temperature and alcohol content in a vehicles fuel system. The sensor contains a pull up resistor to 5v and pulses to ground, producing a variable frequency output corresponding to the ethanol content. The sensor's signal wire also produces a variable pulse width output which can be calibrated to read the fuel's temperature. This sensor has quick connected style fuel connections and a 3-Way F 150 GT Series mating electrical connector.
