|---|---|---|
| Fuel Leak at Filler Neck | Damaged or corroded filler neck, loose connections, faulty O-rings/gaskets. | Inspect the filler neck for cracks or rust. Tighten all connections. Replace the filler neck if damaged, ensuring new gaskets are used. |
| Check Engine Light (EVAP System) | Loose or faulty fuel cap, leak in the EVAP system (which can include the filler neck). | Ensure the fuel cap is tightened correctly. If the light persists, a professional diagnostic scan is recommended to pinpoint the exact leak location. |
