EGT and thermo couple

Recommended Posts

I noticed my EGT gauge was pretty whacky today. It was bouncing up and down, and when I floored it it actually decreased in temp. As soon as I started to back off it would increase. Just kinda all over the scale. I am thinking the thermo couple is going bad. Anyone had this happen before?

No, your fine. You just did not realize the fuel companies have released a new form of environmentally friendly diesel! When you get on the eco-pedal, your engine no longer spews out cancer causing carcinogens, but rather spews out rainbow colored smoke that causes happy thoughts. Which induces people to think about the world more. Then they go off about wanting to eat granola bars and planting trees and hugging bunnies... ...a sad day, indeed. :lmao:

dripley, what gauge do you have?

I have a Banks Dyna fact connected thru a thermo couple. I cant remember if it goes thru the otto mind tuner . but i think not. It has worked fine the past 2 days but still acts up. sometimes I stick my foot to the floor and it hangs. Let off and and it jumps 4 or 500 degrees. Not sure what is happening.

I dont know how to test those but I experienced something similar awhile back with my pyrometer. I have an Isspro and my EGT's were acting up and clearly reading inaccurate. I called Isspro and they showed me how to test both the gauge and the signal box. If either of those checked out then it was the thermocouple. Maybe Banks can do the same for you if you give them a call.

I can tell you how to test your gauge and thermocouple. But if you have a box in between, that is over my head. Read through this and you can get an idea on how to test them. http://forum.mopar1973man.com/threads/5834-Just-can-t-seem-to-get-a-break

I will have to give Banks a call. It worked fine today and yesteday morning, but was a little goofy yesterday afternoon.

Hex response was kind of funny....:lol:But seriously it might be a loose connection, broken wire, or bad probe. Being that both probes and wiring are fairly cheap I would consider just replacing both and go forward...
