Threw a check engine light today. Turned it off with the Xcal2 though. It said...

P1443 EVAP
CTRL VALVE


I found it on this site http://www.paladinmicro.com/PalMFram...&dtc=p1443

But what exactly does that mean? Like what do I have to fix and where are these parts located? Also...what will it ultimately do if it's not fix?


EDIT: Where is the carbon canister located and whats it look like??
