EVAP PRESSURE SENSOR TECHNICAL DATA

Power supply	5V
Differential pressure
-3.7 kPa (-0.37 bar)	approx. 0.5V
0 kPa (0 bar)	approx. 2.5V
1.2 kPa (0.012 bar)	approx. 4.5V

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