Fuel Tank Pressure Sensor

FUEL TANK PRESSURE SENSOR




The fuel tank pressure sensor is installed on the top of the fuel tank and measures the pressure in the fuel tank.

The measured pressure is converted into an electrical signal and sent to the ECM for diagnosis of the evaporative emission control system.
