Thanks, the guy at Oreilly who checked the codes should be able to clear the codes with his scan tool. If not, disconnect the negative cable to the battery for about 10 seconds or so. If it comes back again, either you bought a bad O2 sensor or something else is going on that is triggering the O2 sensor to read improperly. steviej Quote Link to comment Share on other sites More sharing options...
