If you replaced the failing oxygen sensor, you have to wait 3 drive cycles or 40 warmup cycles for it to automatically clear or you have to have the Check engine light code cleared if it's 96 and up. If not, disconnect the battery for 10 min. or more. Connect the battery and it should be off. If it is not then have it read again you may have changed the wrong one.
