2000 Civic Code P1456

Try doing this, while holding the trip counter button, turn the ignition on off on off and then start the engine. Keep holding the button until all the dings and chimes and the engine service light goes off. This may not work on your year car but if it does and then the engine light comes back on after a while, you'll know its something else. If it does not come on then don't worry if the car is running fine. Honda programs the computer to turn the light on from five to seven thousand miles so they can get your money just to scan it and turn it off. Man I hope this helped. Vandragon
