The coolant temp sensor was broken, too. You would think if the temp sensor was bad it throw a CEL.

I'm not sure, but I think there's two. One for the gauges, and one for the computer, but my truck NEVER threw a CEL even though the two didn't jive.
I could be wrong on this, but I seem to remember having to guess at which one it was and I got lucky.
