I have a 2000 honda civic with 93000 miles. It came up with a p1456 code last week, still runs fine. I replaced the gas cap, but the light is still on. Does the civic need to have the check engine code re-set somehow, or do I still have a problem? The code came on last week after driving about 10 minutes. Now it comes on as soon as I start the car.
