VSS not hooked up. you need the speed sensor wire hooked up or you will get bad readings.

Check the temp sensor connection, if thats good swap in another temp sensor to see what it does.

Mine's doing the same thing. I got another temp sensor to try that out. I need to get off my *** and wire it in

I don't know what the VSS has to do with anything.

To compensate for wind cooling maybe?? Just a theory...

Good theory but I dont remember hooking up to a VSS when I did mine. Then again I just do the color coordinated thing so I could have done it without knowing it lol. If the temp sensor is that much of a jump I really have to go with a bad connection or bad sensor.

VSS effects the update rate. Ie it doesn't update while standing still, once you got over 30 it updates instantly. If its not hooked up correctly it will not change more than a degree per minute.

Wind chill is an imaginary number to help you judge how it feels on the skin. The temperature is not changed by wind.

Well I will take a look at the connections at the sensor. I haven't touched anything in the truck so it would be weird for something to get loose there but I guess it can happen. Also my VSS is hooked up. There is a section of road up here I drive on going to campus and it raddles the hell out of my truck.

I would redo the connections on the sensor to start with, I bet corrosion go into the splice.

That's what I am thinking. I'll give it a shot this weekend. What's weird is it worked fine today.

Well it hadn't rained when I first saw it messing up. It was fine again today. I don't know what its deal is. I just got home from college so I'll replace the splices up front this weekend. Its probably corroded a little. Its been on there for 4 years or so.

mine did that before, had just butt connected the wires to the sensor and they had some corrosion and weren't making good contact. I'd recommend soldering being that these are outside of the vehicle.

rewire your connections and use shrink tube and solder it. also the vss is absolutly key. i had mine unused for a week and noticed how erratic is was so i connected it and has been within 5* actual temp.
