Engine code P0446 on a 2003 Oldsmobile Alero indicates an issue with the evaporative emission control (EVAP) system, specifically a problem with the vent control circuit. This could be caused by a faulty vent valve, a clogged charcoal canister, damaged hoses, or electrical issues such as bad wiring or connections. Additionally, it might stem from a loose or damaged gas cap, which can affect the system's pressure. Addressing these components is essential for resolving the code and ensuring proper EVAP system functionality.
