I have a 2014 2500 with a Cummins 6.7, both EGR and DPF deleted. I was at a light to turn. I went and turned right and floored it (mostly, about 75% throttle) and of course a decent amount of smoke came out, I have an MM3 tuner.

At some point the truck "jolted" and I lost power, pretty sure the vehicle went into limp mode. I didn't realize it at the time what it was but I was able to stop the truck and start it again and drive for a few seconds before it went limp again.

I connected a DTC and read the first three attached messages about the exhaust pressure and the gear ratio. I assume the gear ratio errors came up because the truck went into limp mode and the speed wasnt consistent with what the truck was expecting it to be.

Then I tried the old "let's clear it and see if it happens again" thing and I checked the Pending codes and the message about the NOX sensor appeared.

Any ideas what's going on? No other issues nor any problems to date. Maybe just a sensor or a fluke? Haven't had time to drive it again yet. Thanks!

It might help the members to answer your question if you give us know a little more information about the truck, such as year & engine?
