The Check Engine Light comes on after about 5 minutes when I first turn on my car. The car still runs so could it possibly be just an O2 sensor gone bad or anything emission related? If so I can just get it fixed by Honda. I know I can get the number from the green box under the glove compartment, but I haven't done it yet. Also anyone have a list of the problems and the numbers related to it that would turn on the CEL? Thanks
