P2422 Evaporative Emission System Vent Valve Stuck Closed Low
The P2422 code means the vent valve on the charcoal canister has stuck closed. The fuel tank cannot breathe, so you may have trouble filling up or see pressure or vacuum build in the tank. Dirt or water in the valve or its filter is the usual cause.
