UO1OE after replacing DPF Sensor (3rd time in a year)

[motorhead426]

OP’s truck isn’t at a dealer, and the shop has identified the issue.

Towing a truck to Utah isn’t going to do anything but cost money and time lol

Is that the same shop that quoted the subscription fee and the cam twice? Sounds reputable to me . Also, How many times has someone said "the computer needs to be replaced" and it ends up being a ground or something simple. I'm skepticle about the ECM needing to be replaced.

ECM’s go bad sometimes. It happens.

Ironically enough, just went through it on my wife’s car last year, which is also a Stellantis product.

Neither of us are really in a position to judge the quality of the diagnosis from where we sit, to be frank.

The quote was written by a guy in the office off voice notes from the owner/mechanic. I have detailed notes of what all he's done, including calling out failed work by another shop, lab scope results, testing of all wiring and communication, testing of all sensors and communication, and going above and beyond to test everything else before committing to the ECM having failed. It's one CAN bus network in the ECM. Unfortunately, that network can not be replaced. The only fix is to replace the entire ECM.

This guy is primarily a diesel mechanic, and drives Cummins. He's even offered to come move my 5th wheel in the event of an emergency while my truck is down.

I should have gone to his shop first and saved myself $5000 in unnecessary repairs for bogus fault codes being thrown by a failing ECM.

This is just one paragraph of 3 pages of notes he's given me on everything he's done:

Visual inspection under the vehicle definitely indicates somebody has been under here throwing parts at it. Unfortunately none of the repairs were done with any quality. The harnesses are not looped up correctly. The particulate matter sensor connector is broken from the new particulate matter sensor to the module. The module is not bolted in all the way and is missing bolts. The connector from the module to the sensor is actually what is not connected and that is a connector that should have never even been touched in the first place since it comes as part of the sensor. This does not get unplugged during installation.

I feel like the previous mechanic that did that work owes me.

My boss went to the owner of the company I work for (unbeknownst to me) and told him what's going on. He showed up with a company truck and handed me the keys. I'm so grateful.
While I'm sorting this out and saving up for repairs, I have reliable transportation.

Now, if someone wants to give me the winning powerball numbers.... BEFORE the drawing, I'd gladly share the wealth to show my appreciation!

On a side note... I'm on the wrong side of the mountains for Utah to be convenient.
