What Does P2422 Code Mean?

OBD-II Code P2422 is defined as a Evaporative Emission System Vent Valve Stuck Closed

The evaporative control (EVAP) system captures any fuel vapors from the fuel tank and sends them through the vehicle's intake to be burned in the normal combustion process. The EVAP Vent Valve allows fresh air to enter the EVAP system so it is not under a constant vacuum. When the engine control module (PCM) detects the evap system is venting when it should not, it will set code P2422.

Common Problems That Trigger the P2422 Code

• EVAP vent valve failure
• Powertrain Control Module (PCM) failure
• Wiring issue
