I'm a newbie on this site. The 2007 Sienna is my wifes care and it recently came up with the Check Engine Light being on. She had a tire fixed, and the guy at the tire store ran the code and said the O2 sensor was starting to go bad. He gave her a price to replace both of them. The car runs fine and the mileage is the same. So we ignored it. But now its due for an emissions test, and I don't think they will pass it with the light on. I don't know the code. I can get it read and pass that on to you. I heard that the O2 sensor is the part most often replaced when it doesn't need to be. So your suggestions are welcome. I know your first post is going to be "Get us a code!" So I am going to do that. Thanks and Happy New Year!
