You use the button that resets your trip odometer to reset the maintenance light.

with the key in the ignition but not turned on, hold the trip reset button in with one hand. then, while holding the button in, turn the ignition key to the ON position so that the lights on the dash come on.

continue to hold the reset button in and watch the maintenance light. it will take about 15 seconds for the light to go out

when the light goes out, turn the ignition key OFF and then release the trip reset button.

your light will be reset and come on in about another 5000 miles to remind you of the next service

hope that helps

Can't take an OBD-0/pre-OBD car to auto zone as only OBD-2 cars have a hook up for the scanner.

I have a 1990 Honda Civic LX, and the engine light has stayed on for 10 minutes after driving on the freeway and then it stays off for a few days. Is this something that I should be concerned about?


Maybe, your engine has electronically-controlled adjustable valves, one of the modules may be going out on you...but the only way to check that is to actually go to a Honda dealer because most indy shops do not have the equipment necessary to pinpoint which module.

1990 crx base model honda civic want start


I would suggest an ignition module. If it is a rough idle at startup I would check the throttle position sensor. You can check that by starting the car and unplugging the TPS. If the car runs differently then chances are it is working fine.

Honda civic hatchback si it has power till turns the key


It sounds like you have a loose connection at the battery, the door chime and ecm lights don't require much power. As soon as you turn on the key, more power is required, with a bad connection the power from the battery, will drop off. My guess either bad connection at the battery or a battery with a dead cell. Hope this helps.

Engine light is still on after we have replaced numerous parts


The engine light is on, Have u checked for fault codes? To check codes, pull back carpet on passenger side of car to expose ECU (electronic control unit) at 'foot' location on that side. There is a small LED display at the top of the unit, turn the key on (not running) and check for flashes, u must count the flashes to determine what codes are stored in the computer. Short flashes are for codes 1-9, two digit codes use long flashes for the 1st #, followed by short for the 2nd. There is a pause between codes, so there may be more than one. Check and let me know what u find.
