    my father has the same problem with his sensor. the only way to reach it is to remove some hoses around it thats the only way to get to it and on my fathers 02 sienna his sensor is stuck and will not come out so it ended up costing $800 to remove the whole piece and blah blah blah, but we never paid that much so we left it like that but the van still shuts off when turning it on in the morning. it sucks !
