1995 subaru legacy twin turbo manual wagon, the engine check light is spitting out fault code 45, acording to subaru this is the pressure exchange solenoid valve being inoperative or the sensor for it is defective, thus causing the ecu to limit performance and generally make it run like ***, where exactly is the pressure exchange valve and sensor?

Hi I have the same issue, i posted a seperate question, did you find a resolve?
It is one of two places, the differential pressure sensor is o/s/f bulkhead.
Air pressor sensor solenoid is in the solenoid/ vac box o/s/f inner wing (rhd) I think it is the second solenoid I am trying to clarify this as I do not know which is relevant to TC45. just waitin on some more info...
