What to do with Code PO442 on 2004 Grand Am?

Code PO442 on a 2004 Grand Am indicates a small leak in the evaporative emission control system (EVAP). To address this, first, inspect the gas cap for proper sealing and any cracks or damage; replacing it may resolve the issue. Next, check the EVAP hoses and connections for leaks or blockages. If the problem persists, consider using a smoke test to identify leaks in the EVAP system.
