I have a 2015 Ram 1500 ecodiesel that is deleted. And it stalled out on me going down the road. The code it was reading was for the crankshaft position sensor. Which I see is a recall. I’m wondering if the dealership will fix the recall and if the computer being flashed will delete the tune and put the truck in limp mode. I do not have a tuner to put the flash back on. This is why it’s bothering me to get it done.
Even without it being deleted, Steallantis/FCA/Ram Cares won't do a single thing to help you with the issue. The actual issue isn't the CPS, it's that the tone wheel that signals the CPS has a magnetic coating and over time, that coating delaminates. The software flash (W58) simply reroutes from the CPS to the camshaft position sensor and allows the truck to go into limp mode instead of the engine completely cutting out when the tone wheel delaminates. The tone wheel will have to be replaced (and probably the CPS too b/c when the tone wheel goes, it damages the CPS) and that involves dropping the transmission to get access to the CPS and the tone wheel.
The manufacturer used the software flash to CYA so your truck/Jeep didn't cause an accident by the engine going dead while driving. It never addressed the faulty tone wheels and it allowed them to not have to recall over 80,000 trucks and physically replace the bad tone wheels. Which allowed them to run out the clock on the warranty (X96) which was supposed to be 8 years or unlimited mileage-whichever comes first. The warranty period expired in October of 2023. The recall started in 2021 but the 8 years starts on the manufacture date.
The code that comes up is P0336.
I know all this because I'm currently going through this same thing with an undeleted 2015 Ram Ecodiesel myself. It's been a nightmare. I finally got tired of waiting/fighting with Steallantis and paid for the parts and repairs out of my own pocket. My truck went down on April 30th and I just got it back YESTERDAY. My truck was towed 5 different times (3 times to different dealerships, where one absolutely refused to even look at it due it being recall/warranty related) and waited over 2.5 MONTHS for a tone wheel because they're on nationwide backorder.
I started a case with FCA/Steallantis and it's still ongoing even though they have flatly refused to assist in any repairs. I even made a complaint with NHTSA and they won't do diddly because the recall isn't considered OPEN anymore. There was follow-up recall (W66) for folks that DID NOT get the software flash (W58) where they claim that they'll replace the tone wheels and pay for the repairs but they won't. Basically, you're probably screwed and will have to pay for the repairs/parts out of pocket unless you have better luck than I did.
