2000 Alero DTC PO440
My daughter has this car and she had it scanned and this code came up. We looked it up and one of the things was a loose gas cap. She checked her gas cap and it was loose. I took the battery cable off for awhile to reset SERVICE ENGINE SOON Light, but it didn't do any good.
Is there another way to reset this light, so we can see if the loose gas cap was the problem. Thank You!
