why does my Skoda Octavia's engine light stay on after repairs

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to ensure safety during repairs.

2. Inspect Components

• Sub-steps:
  1. Reconnect the battery and start the engine.
  2. Use the OBD-II scanner to read the error codes again.
  3. Identify any recurring codes that may indicate unresolved issues.
  4. Check electrical connectors for damage or corrosion.

3. Addressing Fault Codes

• Sub-steps:
  1. If error codes indicate a specific sensor failure, replace the faulty sensor (e.g., oxygen sensor).
     • Tools: Socket set, torque wrench.
     • Parts: New sensor as per vehicle specifications.
  2. If a problem with the catalytic converter is indicated, inspect for blockages or damage and replace if necessary.

4. Final Checks

• Sub-steps:
  1. After repairs, clear the error codes using the OBD-II scanner.
  2. Monitor the engine light during a test drive to ensure it remains off.
  3. Recheck fluid levels and top off if necessary.
