1999 Honda accord check engine light on?

My car was running good I parked the car go to the store came back and the check engine light came on it makes no noise nothing it still running good

The light doesn't mean the car is making noise or isn't running well. It's a general fault indicator for anything that the computer sees to be out or range.

Want to find out why it's on? Use an OBD reader or get a shop to do it. It'll spit out a code that will say what the issue is.

Well we can't drive it to the auto store to have the codes read so I guess it's up to you to do it!
