scr warmup

[Mudflap77]

Thanks Rawze,
That's was I was trying to get figured out.
What has been throwing me off is that it only happens during scr warm up.
Egr cooler is amazingly still original and is clear no blockage, was cleaned out last year when I was having aftertreatment issues, I visually checked it and a the piping a few weeks ago. I'll take a closer look at the sensors that were replaced, I have gotten a aftermarket sensor in cummins packaging before.
Cummins program matches engine serial #. As far as I know there hasn't been any new updates since it was updated last.
Turbo and actuator was replaced last year due to there being a tough spot when moving the ring arm. Will have to look into the turbo model.
Thanks agian Rawze and Jim T
