If I understand this right when the brake is released the pressure should dump to release the boost, yes.
On the no MPH and FX3 code 23, manual says rt. front sensor. I have too many things on my plate now. That will have to wait until later in the week.

Code 23 for the FX3 I thought was generally set when the key had been cycled 3 times and the car hasn't been moved. I think it also stays as a H code so it's suggested to clear it. You mentioned NO MPH also though and that I believe would hint that there's a VSS issue and that also would set the 23. I'm pretty sure. Your car is a '92 maybe? If you don't have a speedo issue the 23 SRC code should go away by just driving it.
