Messey, have not had any sensors go bad or act up. I would be extremely cautious of the mechanics that have very little experience/knowledge with these babies and start blaming/replacing sensors just because they don't have a clue. If you are having very many sensors failing, then I would think maybe it would be something common to all, like the main computer or something.

But, if what they are doing fixes your problems, then you can only hope that all of the sensors will have been replaced soon.

Keep us informed.
