Fuel Tank Pressure Sensor

RANGE -25.89 to +32.45 mm Hg
The Fuel Tank Pressure (FTP) sensor measures the difference between the pressure or vacuum in the fuel tank and the outside air pressure.

RANGE - 0.0-5.0 Volts
The fuel tank pressure sensor measures the difference between the pressure or the vacuum in the fuel tank and the outside air pressure. When the air pressure in the fuel tank equals the outside air pressure, the output voltage of the sensor is 1.3 to 1.7 volts.
