factory pyro going out?

[travisH3]

Hey guys,
My EGT pyro seems to be off reading it through my mini maxx. When it was zero degrees out and my truck was sitting at work for 10 hours out in the parking lot, when i went to start my truck it said my EGT's were 90 degrees before the truck was started(while I waited for glow plugs) and then lately I have been pulling in the driveway and its dang near its low 300 and into the 200's by the time i put it in park.... I know the sensors in the dpf are the same but I would rather just buy a new one and not mess with removing them from the dpf.

My question for y'all is when you turn the key on with the engine off, is the EGT gauge suppose to be close to the outside temperature if the truck has been sitting and is cold? and does your guys truck get to under 300 that fast? My 6.0 was in the 400's when i put it in park and had to wait a minute for it to get under 350 to shut it off.

Thanks!

Mines been acting the same way. After talking to doss about it he thinks it's the egt sensor on the passenger side right behind the inner fender. It's a biatch to get to so I haven't done it yet

If you are going to replace it, cut the end off of it so you can get a 6 point socket on it to break it loose, also soak with pb blaster thoroughly.

Haha alright. I will get one from my buddy and see what it does. I find it hard to believe my egt's are this low but maybe i just ain't been paying enough attention

When I'm cruising mine will go to 90-245-590-495-75-189-99-89-497. At idle it'll go to 90-125 and back n forth very rapidly. Been doing that for a while now, even does it with my edge cts insight too. I'm thinking if I can remove or get the inner fender loose I'd be able to replace it but idk how hard it is to get the inner fender out

Yours Is definitely worse than mine then. I think it's doable from the bottom if you cut the old one to get the box end on it. Then use a ratcheting wrench and it should be easy.
