How do you turn off check engine light on a 1992 Honda Accord?

To turn off the check engine light on a 1992 Honda Accord, first, you need to diagnose the issue triggering the light by using an OBD-I scanner or checking for any stored trouble codes. Once the problem is resolved, you can reset the light by disconnecting the negative battery terminal for about 10-15 minutes. Reconnect the terminal, and the light should remain off if the issue has been fixed. If it comes back on, further diagnosis may be required.
