Well I tried searching for the thread but I couldn't find it. Anyway, as mentioned previously my outside temperature read out was always off by about ~10 degrees under and although that TSB floating around said something about it being normal and crap I decided to bite the bullet and buy a outside temp sensor and install it. Guess what? It fixed it! So I call bulls*** on that TSB. If your outside temp read out is off and not reading correctly please disregard that bulls*** TSB from Mazda that's says its normal and replace or have them replace your outside temp sensor if you're under warranty.
