Why would the check engine light come on in 2000 Honda Accord?

Have someone pull the codes from the computer...Most likely it has to do with your emission control system.Did you fill-up your tank recently?

Sometimes my check engine light comes on if I don't screw the gas cap on tight enough. You should probably get it checked out either way. I think Aamco will do a free inspection (they just hook a machine up to your car's computer to see why the light came on). Hope that helps.

most likely it is a sensor malfunction or you can try the oxygen sensor that most likely is the reason

Hello, Honda-people.

I have a 2003 accord, and i am having major problems with my oxygen sensor. I have replaced it twice now, and the stinking check engine light continues to turn on with the same codes, which identify the oxygen sensor as the problem. I hate to go to the dealership, because they are so ridiculously over priced, but the mechanic I took it to has no answers, and the oxygen sensor obviously isn't causing the problem. Now I'm out $300 and still haven't fixed the problem. Anyone have any problem with the same thing and find the solution? Please help!
