AC pressure sensor?

AC pressure sensor?
Hi
I just got CEL on my S70 this morning, 2 codes: p0446 (Evaporative emissions control vent circuit low) and p0531 (ac pressure sensor circuit performance/range).
- had a cracked "j hose" and i was hoping that replacing it would take care of first code but it didnt?! What else can trigger this code?
-I did search on second code and no luck. My ac works when I first turn it on and it shuts off after few minutes. I thought this means bad clutch on compressor? but this code for ac pressure sensor makes me wonder if its something else? Which sensor is this, where is it located?
Any help would be greatly appreciated

Hoses were fine. Shut off valve was the problem. I replaced it. No more p0446 code.
I changed high pressure switch as well, nothing changed, i only have ac for first 5 minutes. I think i am going to replace ac compressor because clutch is probably gone and then see if code comes back.
thanks tech!
