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.

I had the Check Engine light come on second time. First time it went away after the gas tank cap was tightened. But this time it did not. Toyota recommended take to dealer. Somewhere on the web I found suggestion to unplug the battery and see. I did and the light went away. You might want to try this first.
