How To Reset Check Engine Light Honda Accord 2013

The check engine light on a 2013 Honda Accord can be reset by disconnecting the battery, using an OBD-II scanner, or driving the vehicle for a certain period after fixing the underlying issue. However, it’s crucial to diagnose and address the root cause before attempting to reset the light.

Check Engine Light Explained

The check engine light in your 2013 Honda Accord is part of the onboard diagnostics system. It illuminates when the vehicle’s computer detects a problem related to the engine, transmission, or emissions control system.

Common reasons for the check engine light to come on include:

• Loose or faulty gas cap
• Malfunctioning oxygen sensor
• Failing catalytic converter
• Worn spark plugs or wires
• Issues with the mass airflow sensor

When the light comes on, it’s important to take action promptly to prevent potential damage to your vehicle and ensure it’s running efficiently.

Diagnosing the Issue

Before resetting the check engine light, it’s crucial to diagnose the underlying problem. Here’s how to do it:

1. Use an OBD-II scanner: Connect a scanner to the diagnostic port under the dashboard to read the error codes.
2. Check for obvious issues: Inspect for loose wires, vacuum hoses, or a loose gas cap.
3. Monitor vehicle performance: Pay attention to any changes in fuel efficiency, engine power, or unusual noises.
4. Professional diagnosis: If you’re unsure, have a certified mechanic inspect your Accord.

Remember, resetting the light without fixing the problem may cause it to come back on shortly after.

Method 1: Disconnecting the Battery

To reset the check engine light on your 2013 Honda Accord by disconnecting the battery:

1. Turn off the engine and open the hood.
2. Locate the battery and identify the negative terminal (marked with a “-” symbol).
3. Use a wrench to loosen the nut on the negative terminal.
4. Carefully remove the negative cable from the battery terminal.
5. Wait for about 15 minutes to ensure all residual power is drained.
6. Reconnect the negative cable and tighten the nut securely.
7. Close the hood and start the engine.

This method will reset all electrical components, including the radio presets and clock. It may also temporarily affect the vehicle’s idle speed and transmission shifting until the computer relearns these parameters.

Method 2: Using an OBD-II Scanner

Using an OBD-II scanner is the most efficient way to reset the check engine light:

1. Locate the OBD-II port under the dashboard on the driver’s side.
2. Plug the scanner into the port.
3. Turn the ignition to the “On” position without starting the engine.
4. Follow the scanner’s instructions to read the error codes.
5. Write down the codes for future reference.
6. Use the scanner’s “Clear Codes” or “Erase Codes” function.
7. Turn off the ignition and unplug the scanner.
8. Start the engine to verify the light has been reset.

This method is preferred as it allows you to identify the specific issue before clearing the codes.

Method 3: Drive Cycle Reset

After fixing the underlying issue, you can reset the check engine light by completing a drive cycle:

1. Start the engine and let it idle for at least one minute.
2. Drive the car for about 10 minutes, maintaining speeds between 30-50 mph.
3. Let the car idle for another 30 seconds.
4. Repeat this process 3-4 times.

This method allows the car’s computer to run through all its self-check routines and clear the error if the problem has been resolved.
