Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Gas Cap

Remove the gas cap and inspect for cracks or wear.
If defective, replace with a new OEM gas cap. Tighten securely.

3. Inspect and Replace Purge Valve

Locate the EVAP purge valve (usually near the engine or intake manifold).
Disconnect the electrical connector and vacuum lines.
Remove the purge valve using the appropriate socket.
Install the new purge valve and reconnect the vacuum lines and electrical connector.

4. Inspect and Replace EVAP Canister (if needed)

Locate the EVAP canister, usually underneath the vehicle near the fuel tank.
Remove any screws or clips securing the canister.
Carefully detach the canister from its mounting brackets.
Inspect for damage; if cracked, replace with a new canister.
Reinstall the new canister and secure it with the screws or clips.

5. Clear Codes and Test Drive

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear the P0441 code.
Start the engine and take the vehicle for a test drive to ensure the code does not return.
