|---|---|
| Po441 | Incorrect Purge Flow in EVAP System |
How The Evap System Links To P0441
The EVAP system captures fuel vapors from the fuel tank. It prevents these vapors from escaping into the air. The system stores the vapors in a charcoal canister. Later, the engine burns these vapors.
Several components make up the EVAP system:
- Charcoal Canister
- Purge Valve
- Vent Valve
- Fuel Tank
- Fuel Cap
If any of these components fail, it can trigger the Po441 code. A common cause is a faulty purge valve. This valve controls the flow of vapors from the canister to the engine.
Another cause could be a leaky fuel cap. Always ensure the fuel cap is tight after refueling. A damaged charcoal canister can also lead to this code.
Understanding the EVAP system helps in diagnosing Po441 issues. Regular maintenance can prevent these problems.
