why does my Honda Accord 9th Generation (2013-2017) engine light stay on

Solution

1. Preparation

• Gather tools and parts.
• Ensure the vehicle is parked on a flat surface.
• Disconnect the battery to reset the engine control unit (ECU) after repairs.

2. Address Fault Codes

• If codes indicate a specific issue (e.g., P0420 for catalytic converter efficiency), focus on that component.
• For a misfire code, replace faulty spark plugs and ignition coils as necessary.

3. Inspect and Replace Components

• Gas Cap Replacement:

  • Remove the old gas cap.
  • Install a new gas cap, ensuring it clicks securely.

• Spark Plug Replacement:

  • Remove the ignition coils using a socket set.
  • Remove the spark plugs with a spark plug socket.
  • Install new spark plugs and torque them to the manufacturer’s specifications (typically around 13 lb-ft).
  • Reinstall ignition coils.

• Vacuum Leak Repair:

  • Inspect all vacuum lines for cracks or disconnections.
  • Replace any damaged hoses with new ones.

4. Reset the Engine Light

• Reconnect the battery.
• Use the OBD-II scanner to clear the trouble codes from the ECU.
