Check eng light and trac off codes went came on (together) 2 wks ago and I took my 2000 ES to a dealer (mileage 65,000). It cost me $431.00 to have them replace the Air fuel oxygen sensor (Bank 2, sensor 1). Well, now both came on again....I cleaned my gas cap and re-set my battery which fixed the problem initially but a few minutes later it came on again. I'm presuming it may be one of the other two sensors? Anyone have any ideas?

Thanks,

Agreed, you need to get the codes before you do anything else. Once you have codes we can assist.

Thanks for your offer. I actually schedued an appt w/Lexus to take a look at it and they claim they'll do a "complimentary" diagnostic test. If it comes up with a faulty sensor (the one they supposedly fixed), then they fix it at no charge. We'll see...i'll let you know what they find.
