Yes you were right...it came on next day...I took it to Advanced Auto Parts and got the Oxygen sensor code PO 135 which I gather is front passenger side..I'll be taking it to the dealer..hope it is covered under the 90 k 7 year warranty I've seen in the Owner's manual. I've owned Toyatas since 91 and feel their quality and reliablity has been going down esp as manufacturing shifted out of Japan. I still have 91 camry which runs fine.
