Fuel Tank Differential Pressure Sensor

A voltage proportional to pressure in fuel tank is sent from output terminal of fuel tank differential sensor to PCM. PCM monitors performance of Evaporative Emission Control System (EVAP) system using these signals. It also uses input from Fuel Tank Differential Pressure (FTDP) sensor to monitor EVAP system pressure changes and calculates whether leak exists.
