i coded my pony and I got an 02 sensor problem. I think it was a grounded wire so I grounded it and I coded it again and it came up again. Do I have to drive the car for a little bit for the codes to clear or do I still have a problem?
While you have it displaying the codes just disconnect the jumper wire and the stored codes will reset. After you do this try and retrieve the codes again to check that they have cleared. Then drive the car for about 20 miles and follow up to see if the problem arrises again.
