P2422Evaporative Emission System Vent Valve Stuck Closed

P2422 means the powertrain control module has commanded the evaporative emission system vent valve to open, but the valve has remained stuck closed, so the system cannot vent fuel vapor to the charcoal canister. The computer detects this by monitoring the fuel tank pressure sensor or a dedicated vent valve position sensor and seeing no expected pressure change when the valve is commanded.
