Fuel Tank Differential Pressure Sensor

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