Methods to Reset the Light
There are several methods to reset the check engine light on your Honda. Choose the one that suits your situation best.
Using an OBD-II Scanner
One of the most efficient ways to reset the check engine light is by using an OBD-II scanner. This tool connects to your vehicle’s diagnostic port and provides real-time data about the engine’s performance.

- Plug in the scanner and turn on the ignition without starting the engine.
- Follow the scanner’s prompts to read the trouble codes.
- Once you’ve noted any issues, select the option to clear the codes.
- Disconnect the scanner and start your vehicle to see if the light is off.
Disconnecting the Battery
If you don’t have access to an OBD-II scanner, disconnecting the battery is a classic method. This can reset the vehicle’s computer and turn off the check engine light.
- Ensure the vehicle is turned off and in park.
- Open the hood and locate the battery.
- Using a wrench, disconnect the negative terminal (usually marked with a minus sign).
- Leave it disconnected for about 15 minutes.

Driving Cycle Reset
Sometimes, the check engine light will reset itself after a certain number of driving cycles. If you’ve fixed the issue, simply driving your Honda for a while can do the trick.
- Drive your vehicle for at least 50-100 miles.
- Ensure you go through various driving conditions: stop-and-go traffic, highway speeds, and idling.
- Monitor the dashboard to see if the light turns off.
When to Seek Professional Help
If the check engine light remains illuminated after trying these methods, it’s time to consult a professional. Ignoring the light can lead to more severe issues down the line.
