1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety goggles and gloves.

2. Inspect and Replace the Purge Valve

Sub-steps:
1. Locate the EVAP purge valve, usually found near the intake manifold or on the EVAP canister.
2. Disconnect the electrical connector from the purge valve.
3. Remove any hoses attached to the purge valve by loosening the clamps.
4. Remove the purge valve from its mounting.
5. Install the new purge valve by reversing the removal steps. Ensure tight connections on hoses and connectors.

3. Inspect and Replace Fuel Filler Cap

Sub-steps:
1. Remove the fuel filler cap and inspect the rubber seal for cracks or wear.
2. Replace the fuel filler cap with a new OEM or equivalent part.
3. Ensure the cap clicks securely into place when reinstalled.

4. Clear Codes and Test

Sub-steps:
1. Use the OBD-II scanner to clear the P0441 code and any other related codes.
2. Start the engine and let it idle for a few minutes.
3. Take the vehicle for a test drive to ensure the check engine light does not reappear.
