Most air mass flow sensors are simple potentiometers. If there are three connections, it is easy to determine what the voltage range will be. Measure the two outside terminals of the pot (not the wiper) and that is the reference voltage voltage number you are looking for. The reference voltage will not change as the sensor changes, only the voltage at the wiper will change.
