Trouble finding a part for my truck

What engine and make of truck?
You could have a broken with causing the problem.

 

Same here, I had no idea you could pull codes from the app.

 

Have you tried contacting a Cummins dealer?

 

So just changing components because there is a fault related to it? I'd at least take a look at the wiring and connections before implementing the pick-a-part-and-pray method.

 

That's telling you you have a wiring harness problem, not a bad sensor.

 

It looks to me it could very well be a wiring problem.
The codes you have there are for two very different circuits in the same sensor.
Common sense diagnostics dictates that the odds for two separate circuits of the same sensor to fail simultaneously are not very likely.
When this kind of problem occurs it’s usually damaged wiring or corrosion in a connection somewhere.
The first question I always ask is “was there anything done to the truck repair wise recently when you noticed this issue “
A quick case in point is I had a dodge 3500 come in the shop with a cruise control failure.
I ask the owner if any repair work was done recently and he said no.
I started testing and the shop phone rang and it was the owner of the truck who said “ this probably has nothing to do with it but I had a windshield put in two weeks ago”
Well I started looking and found where the windshield repair company got a little crazy with their electric knife cutting out the windshield.
There was a small gash cut through the vacuum tank up by the windshield that caused the cruise control problem.
Was the windshield put in before you had this issue?
If the issue occurred after the windshield replacement check for wiring damage around that area.

 

Sounds like connector with salt or water intrusion.
Find the sensor and pop the connector open and see what you have there.
If you don’t find it there work your way back towards the ECM checking all the junction plugs as you go.
Make sure you use dielectric grease in all connectors when reassembling.
