I failed a smog test because there was no data from OBS test for oxygen sensors. I passed all the emission requirements. I have heard there is a way to reset the data by driving certain speeds for specific distances. Does anybody have information on this problem?

could they not communicate with the obd connector? If not, check your fuses, especially the one for the cigarette lighter.
