Hello all, I bought a 2006 TBSS not too long ago and after fixing some basic issues, the truck would shut off when it would hit about 170-180 degrees. Upon shutting off, it would throw code P0601, which I found very little information on. After some progressive diagnostics I ended up solving it. If you're having the same issue, please see my video, it shows steps you can before buying a new PCM.
