M11 Oil Pressure PDI100 FM1

Long story short I've been chasing an intermittent problem where my truck will just shut down randomly with no apparent rhyme or reason. It is a 1997 International 9800 with a M11 Cummins.
I found a loose connection under the dash and thought that was the problem. We took it on a 9 hour road trip and it did great until we were almost home when it shut down while driving and then again 10 miles later and drove great after that the rest of the way home.
I ordered a cheap autel scan tool to see if it has codes, even though I have no dash warning light on at all, even when it shuts down.
I do have an active code though: PID100 FM1 Oil pressure below operating range- most severe.
The gauge on the dash seems to be reading fine (25-50psi) so I looked at the data though the scan tool and it said I had almost 100PSI.
I change the oil pressure sensor and now the data on the scan tool and my dash gauge are within 5psi of each other.
The code is still active though.
Any ideas where to go from here? It looks like the ECM is getting the correct oil pressure so I'm not sure what would be causing the code.

 

It’s staying as an active code so I can’t clear the code, well atleast not with my scan tool

The thing thats throwing my off is that the data on the scan tool is showing good oil pressure and that should be seeing what the ECM sees

Definitely won’t hurt the clean all the connections and inspect the wires too

 

I haven’t seen one on it
It does have the Cummins engine protection built in though

That’s my bad, I forgot the I
