How to Fix Error Code P0500

  1. Check for symptoms and verify the code

    Ensure the parking brake is engaged and the vehicle is on level ground before diagnostics.
  2. Inspect the vehicle speed sensor wiring

    Disconnect the battery negative terminal before working on electrical connections to prevent short circuits.
  3. Test the speed sensor signal

    Never work under a vehicle supported only by a jack - always use jack stands for safety.
  4. Check the transmission output shaft

  5. Replace the vehicle speed sensor

    Use only the correct replacement sensor for your specific Subaru model and year to ensure proper fit and function.
  6. Clear codes and test drive

    Test drive in a safe area with light traffic to properly evaluate all vehicle systems.
