Code P0449 on a 2003 Buick Rendezvous indicates an issue with the evaporative emission control system (EVAP), specifically related to the vent control valve. To fix it, first inspect the wiring and connectors for any damage or corrosion. If they appear fine, test or replace the vent control valve itself, which is located near the fuel tank. Additionally, check for any leaks in the EVAP system, including hoses and the gas cap, to ensure a proper seal.
