POWER SUPPLY REFERENCE CHART

Power supply	V	5
Differential pressure
-3.7 kPa (-0.37 bar)	V	approx. 0.5
0 kPa (0 bar)	V	approx. 2.5
1.2 kPa (0.012 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.
