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
