I have been looking at info on our boost sensor, here are my findings. Volvo part # 30622083, Original Bosch # 0 261 230 106 replaced by Bosch # 0 261 230 042. It has a pressure range of 20-250 kPa it also has a NTC sensor (or a IAT) built in with a range of -40* to +130*C.
Electrical pin designations are #1 = ground, #2 = NTC resistor, #3 = +5VDC (from ECU), #4 = Boost signal.
I logged the boost signal with a VOM. These readings are with the 5 year old original sensor on my car and may not be accurate. Also note that I am about 600 feet above sea level. These readings were taken with ignition switch in run position, engine stopped. VOM connected - to pin 1, + to pin 4. Also note an air pressure source was connected to boost sensor through an adjustable pressure regulator.
0 psi 1.55 vdc
1 psi 1.65 vdc
4 psi 1.95 vdc
5 psi 2.05 vdc
10 psi 2.65 vdc
15 psi 3.15 vdc
16 psi 3.25 vdc
17 psi 3.35 vdc
18 psi 3.45 vdc
19 psi 3.55 vdc
20 psi 3.65 vdc
It can be noted from the above that each additional 1 psi results in an increase of 0.1 vdc.
If you have any other info please post it below, ie where to buy and price or other technical info.
