Going to run it and probably won't see it happen again. Least I hope not. Would be a drag if truck would only run at idle due to throttle pedal not working.

I think Cummins says after 3 successful test the CEL will go out. Possibly could have had the slightest bit of moisture on a connector on morning start up and threw the code. Engine warms up, moisture dries up, code goes inactive. I just read through the shop talk about this code and I'm pretty convinced that's what happened.

A common theme prevails: 1) CEL comes on, 2) EGR is disabled 3) Possible loss of power

A never-ending cycle.
