-40f

Whoa, just the first days of Autumn and its already -40F according to the overhead, YIKES!!!. And I was caught without a coat.....

Today's temp reading is more normal. This is probably an intermittent open temp sensor circuit (or failing sensor), right?

Thanks, I saw that TSB, but the display stayed at -40 for an hour. When I started up this morning it was back to normal....

I have always disconnected my neg battery cables for various little problems. This one, a time when my dome lights stayed on too long after I locked the truck, once when they went out too quick etc... Disconnected for about 15 minutes and never had the problem again!

It's a intermittent thing and can only be fixed if you have the TSB done.
