Canister Close Valve: Notes
WARNING: This page is about a different car, the 2004 Hyundai XG350. However, it is still accessible from the selected car via links, so may be relevant.
The Canister Close Valve (CCV) is for monitoring of evaporative leakage detection.
While the leakage monitoring is operated, the CCV becomes closed but it is normally open.
