Here in NC they dont do sniffer tests on OBD-II cars they only run for codes and make the CEL come on because i have the DMV regulations on it, i would get those to see how they are sposed to test it I.E. wht all is involved, because i no if they failed me because of a sniffer test and weren't sposed to snifer test to begin with i would show them the regulations and raise hell about it
