turn the key to activate the power but not start the ignition, do this a handfull of times. The check engine light should blink a specific number of times, this can be referenced to identify the problem, after this happens the light should turn off until you have another problem!
There's a difference between the "check engine" light and the "engine maintenance required" light (aka "Emission Maintenance Reminder" or EMR light). The EMR light is strickly a reminder that emission system maintenance is due. This includes the EGR valve, PCV valve, & Oxygen sensor. It is program to light at approximately 60,000, 82,500, & 120,000 miles. Because its activated by mileage, it does not necessarily mean that something has malfuction. Unfortunately, the only way to reset it is by using a diagnostic scan tool. Of course, you could always remove the bulb.

What does it mean when the maintenance light of a 1991 Honda Accord is on?
The maintenance light on all early model hondas have three stages. Green, orange and then red. This light only serves as a reminder to change your oil, air filter and to do other routine maintenance. If you were to service the vehicle and not reset the light it would just stay on. It changes color by miles. It's green when it is reset and as you drive it will eventually change to orange and then red regardless of any services done to the vehicle. To reset look on the instrument panel for a slot near the light and insert your key this will change it back to green.
