What is the P0441 Code?

The P0441 code is a diagnostic trouble code (DTC) that indicates an issue with the evaporative emission control system (EVAP) in your Subaru Outback. Specifically, it means that the system is not functioning as it should, which can lead to increased emissions and potential performance issues.

Key Points:

  • DTC: P0441
  • System Affected: Evaporative Emission Control System
  • Common Symptoms: Check Engine Light, decreased fuel efficiency

Causes of P0441 Code

Understanding the potential causes of the P0441 code can help you diagnose the issue more effectively. Here are some common reasons why this code may appear:

  1. Faulty EVAP Purge Valve: The purge valve controls the flow of fuel vapors from the charcoal canister to the engine. If it’s stuck open or closed, it can trigger the P0441 code.

  2. Clogged Charcoal Canister: The charcoal canister absorbs fuel vapors. If it becomes clogged, it can disrupt the EVAP system's function.

  3. Leaking Hoses: Cracks or leaks in the hoses connected to the EVAP system can lead to improper pressure and trigger the P0441 code.

  4. Faulty Fuel Cap: A loose or damaged fuel cap can allow vapors to escape, causing the EVAP system to malfunction.

  5. Electrical Issues: Problems with the wiring or connectors in the EVAP system can also lead to the P0441 code.
