Engine stop light

2008 HR Endeavor 8.9 ISL Cummins
Changed out a blown EGR cooler after an overheat due to a serpentine belt failure.
All is normal now except my stop engine light is on.
Engine is staying cool, coolant flow is good. Took it for a drive and it did two regen cycles. The first one I was unable to maintain rpm due to construction so it shut down the regen.
Second regen worked normal
No white smoke or any coolant in the oil.

Any thoughts on which sensor Will be the culprit?
Possible DPF clogged due to coolant contamination?

You need a code scanner/reader to know what is going on. I recommend the ScanGauge D. https://www.scangauge.com/products/scangauge-d/

It's inexpensive and in addition to reading fault codes, it can also display engine and transmission data (coolant temp, boost, oil press, rpm, speed, etc.). There are dozens of engine and trans data elements it can display (four items on the screen at a time).

Or take the Coach to a shop and have the codes read. Don't take a chance hoping the light will go away by itself.

PS. There may be a way to read the fault codes without any tools/readers. Many diesel Coaches will let you read fault codes by counting the number of check engine light blinks. In those Coaches you activate the "code blink" using the Cruise Control switches. Check you Owners manual for the instructions.
