2016 Lonestar Cummins ISX15 CM2350 Odd Situation

[Rawze]

If you suspect wiring issue then go to quickserv.com, register the engine ser#, and go have a look at the ECM wiring diagram, see if there are any common voltage supplies, etc. going to those sensors.

You have to also consider the wiring harness itself, such as a connector that is common to those senspors that might have moisture in it.

Ambient air sensor and accelerator fault codes are not normal at all. They don't come up unless you have real issues... and are often seen when water/moisture gets into connectors/plug... typically after some idiot uses a power-washer under the hood to clean on and around the engine (this is very a bad thing to do to any vehicle engine compartment). - Many a trucker finds this out the hard way after going to a truck-wash and not telling the idiots 'NOT' to clean the engine areas.

The 3567, 4572, and 4677 are associated with a J1939 communications issue on the harness going down behind the engine and to the aftertreatment systems. - Same thing, likely moisture or corrosion in a harness plug, or maybe where the wiring has started rubbing thru in some place as it snakes thru the frame back behind the engine.
