EVAP PRESSURE SENSOR DESCRIPTION

Location		On fuel tank by petrol pump
Power supply	V	5
Differential pressure
-3.75 kPa (-0.0375 bar)	V	approx. 0.5
0 kPa (0 bar)	V	approx. 3.5
1.25 kPa (0.0125 bar)	V	approx. 4.5

The pressure sensor determines the difference in pressure between the tank and the atmosphere, and supplies the control module with a proportional voltage.
