Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery (negative terminal) to prevent electrical shorts.

2. Inspect and Replace the Gas Cap

• Remove the gas cap and inspect the sealing surface for wear or damage.
• If damaged, replace with a new gas cap.

3. Inspect EVAP Hoses

• Trace the EVAP hoses from the fuel tank to the purge valve.
• Check for any cracks, kinks, or disconnections.
• If any hoses are damaged, replace them with new hoses.

4. Test and Replace the Purge Valve

• Locate the purge valve (usually near the engine).
• Disconnect the electrical connector and hoses attached to the purge valve.
• Using a multimeter, check for continuity across the valve terminals.
• If the valve is faulty, replace it with a new one.
• Reconnect all hoses and electrical connectors.

5. Perform a Smoke Test

• Attach a smoke machine to the EVAP system.
• Observe for smoke escaping from any leaks.
• If leaks are found, repair or replace affected components.

6. Clear Error Codes and Reconnect Battery

• Use the OBD-II scanner to clear the P0441 code from the vehicle's computer.
• Reconnect the battery terminal and ensure it is secure.
