Dealer "can't figure out" these codes?

[jdksla]

New (used) 2015 RAM 2500 Cummins 4x4 long bed (yay me). Over 70k miles.

First night home, check engine light comes on.

FAULT: 05 PEND: 02

P2228 01/07
P1193 02/07
P0102 05/07

Light not on next morning when I start it. Drive around all day. No light. Seemingly no performance problems. Drive for an hour through small hills, neighborhoods, highway, etc. No light.

Go on a 3 mile drive after it's cooled off and light comes on again.

Take to dealer, they can't reproduce. Light won't come on. Finally, a week later, they say they got "some codes" but don't know how to fix them. Great sign, right?

I've read and read on these codes and it could be anything from cheap fix (dirty sensor) to I-don't-wanna-think-about-it.

Anyone have similar codes a 2500 diesel w/ similar mileage?

Checked the air filter just in case.

Since all of those codes are related to sensors on top of the air box, my guess is that something damaged the harness going to those sensors, especially since they are all circuit codes, I would start with a good inspection of that harness.

Time for new Air filter as a minimum




Cannot find the last 1


Does the cummings have the wire that plugs into the MAP/MAF sensor on the air inlet tube past the box??? Just thinking out loud but I do not know much on Cummings Diesel

I just went out and looked at mine, the harness for those sensors goes down besides the alternator and joins into a larger harness. I guess its possible that you have 2 bad sensors, but my first guess is that the harness got damaged since you have codes for sensors that share the same wire harness.

here is a diagram if you need it

That air filter looks TERRIBLE. Have you run the truck with a new filter? I know furnaces much better than trucks but can tell you a filter like that can wreak all kinds of havoc on an HVAC system in a house including the thing cycling on/off and throwing error codes. I wouldn't do another thing until you put a fresh filter in and run it for a while (if you haven't).

I have not replaced the air filter yet. It has been at the dealership since the 19th except for the few hours I had it to myself. They alternate between not knowing what's wrong and just letting it sit in line for the tech to look at it.

Thank you! This is beyond my skill level at this time.

Thank you. If the dealership does not know how to fix it, I will keep an eye on the miles per gallon I'm getting and will inspect this harness.

Talked to mechanic today and he says it's the turbo actuator. Not sure if it needs replaced or just cleaned. Anyway, nice that someone finally took a look at the thing.

Did you get everything fixed?
