Engine code P0449 typically indicates an issue with the evaporative emission control system, specifically related to the vent control valve. To fix it, first, inspect the vent valve and associated wiring for damage or disconnections. If the components are intact, test the vent valve for proper operation and replace it if necessary. Additionally, check for leaks in the EVAP system and ensure all hoses are securely connected.
