Code P1110 guidance?

Recently my 2004 9-5 Arc illuminated the CEL. I checked the codes and found: P1110 - this is the only code.
After doing some searching in the forum, the following seem to be sources of the problem:
1 Vacuum lines
2 turbo by-pass valve (aka Hooter valve),
3 Boost control valve
4 Intake pressure sensor
I did a fairly good check of the vacuum lines and they seem OK and all attached (but I’ll replace them anyway as the car has 120K miles on it – anyone know the ID of the line?)
The real question for me is how to check the turbo by-pass valve and the boost control valve? any guidance welcomed.
I just don’t want to throw parts at the car (even though at 120K it may not be a bad idea)
Thanks
J
