Hi,

@printertosh

I seen in documentation about Differential Pressure Sensor that correct pins are:

1 Pressure information (0,5 to 5 volts)
2 Earth
3 5 volts supply

Voltage supplied for a differential pressure of 0 bar : (± 0,5 volt) (engine off) .
Voltage supplied for a differential pressure of 0,9 bar : (± 4,1 volts) (particle filter clogged).

@fucco

Dummy sensor can be made in the same way I designed the FAP temperature sensor.
I just need some time to study the values he send to ECU computer: pressure - voltage.
