I was hoping to test in place and not remove the gage or instrument. Is there a way to test either continuity or resistance to determine which one is bad? The meter shows 450 degrees fahrenheit no matter what.

you have the coolest running or hottest sitting truck ever
personally I would buy another gauge, test your components separately with the new parts and than return it. With that info you can than order the replacement pieces needed.

I had a pyro gauge that occasionally stuck. I noticed it was reading 600 degrees while going up hill on the freeway while towing. It should have been near the limit of 1200. Anyway, I tapped on the face of the gauge and it popped up to the correct reading.
I'd start by changing out the gauge. Make sure if you switch to a different brand of gauge that the fittings on the back will match.
Good luck.

Only way I could conjure would be to either pull the probe and use a high temp thermostat and compare temps in say a flame using a torch. I'd just be careful because you could fry the probe. What brand of gauge are your refering to? If you knew the specific brand it would reason they might have a tech proceedure to determine if it was good or bad.

It is an autometer gage and probe set up. I stopped by the local Diesel Hot Rod shop and they said they actually think it it is the gage as well. I am going to see if autometer has a repair center or if I just need to buy a new one.

So for anyone wondering how to test an autometer egt gage, this is what the tech dept said to test it:
1. Verify good ground and 12 vdc at gage.
2. disconnect probe and then turn on power to gage, it should read between 0-100 degrees F.
Mine did not. He then said it needed to be repaired / replaced. I will let y'all know how their service department is I guess.
