Electrical expectations

For the life of me i cannot find the expected voltages for the following circuit. It's the 3 wires that connect to the Differentail Pressure Sensor, they are: A41, A44 and A63.

A63 is ground therefore should be 0 volts.
A41 is power and should be 0-5 volts, although this evens out at 2.1 volts,
A44 is signal and should be 5 volts.

Could somebody please confirm or even better do me a screen shot.

Many thanks.

There you go, I'm having the same issue at the moment

I think you have muddled 41 & 44, the power is constant 5V, the signal varies 0-5v
