Temp gauge problems

So my temp gauge only works intermittently. I had it checked out and had a "failure to duplicate". No wiring issues. It will go from a normal temp reading to cold all of the sudden, and my check engine light comes on showing that my temp gauge is out of range. Has anyone ever had this problem? Im not overheating, so im not too worried about it for now

I would check all your connections. Pull them apart, clean them up and put them back together. I would bet you will find one of them is loose.

Check your ground wires. There are a lot of vehicle electrical problems that have poor grounds, corroded grounds, etc. as their root cause. I would find the various grounding points clean then off with emory cloth and then use dielectric paste when reattaching.

I had a similar issue. My temp gauge would quickly dial over to the overheating side when I pressed on my horn. NO JOKE. Apparantly I had a short on my blinker and it was sucking too many amps. The low amps caused my gauge increase. So I guess, you can check your grounds for a fault.

It still seems odd, but I'm very serious. Good Luck!

I was shocked how inacurate the stock guage is. Mine wasn't even close. I would spend a little bit of money and replace the sensor and the guage. You can clean up wiring when you do it. It's a mess in there.

Temp Guage

x2 on replacing. Go the VDO route. You'll be glad.

Agreed. I have a 100% manual thermometer-bulb-type gauge that reads out of the radiator just below the top hose. 100% accurate all the time even when the truck is turned off.
