45 Pressure sensor –Pressure exchange solenoid valve

I don't think this is the boost control soleonoid, but the brown solenoid near-by that has a vacum hose attached one end and a Black tophat type filter pushed on the other end.
It's about half the size of the boost control solenoid.

try giving that a clean with brake/carb cleaner and if possible energise it with a 12V supply while cleaning. Also clean out any adjoining vacum hoses.
