Based on the pressure difference between the tank and atmosphere, the pressure sensor yields a proportional voltage to control module pin 11(A). The
pressure sensor value is adapted to 0 kPa when the ignition is switched on provided coolant temperature is less than 40 °C and fuel level is less than 50
litres.
