Have you disconnected the battery over night after replacing the sensor? If you did not, the codes will keep coming up...

Just disconnect the battery when you get to work, and it should be ready when you leave in the morning

How long did you leave the battery off for? It's supposed to be overnight. Somewhere on here I read > 24 hrs...

in my past experiences i didnt have to leave it off for 24 hours, the last time i did it, it was for no longer than like 4 hours (possibly more, dont remember). that always seems to reset my codes with no prob.

is there a possibility that some codes cant be reset in the shorter timespan? maybe o2 codes require the 24 hours while the others dont?

erasing volatile memory usually doesnt take longer than 15 seconds, on some cars it might be longer, but not in the 'hours'

this of course doenst apply to older cars.

Oreilly's Auto Parts stores, same quality as an AUTOZONE, but my guess is cheaper, but I only paid $70 so...
