Just chiming in with our experience with needing the tone ring replaced. Our truck is a 2015 Ecodiesel with 144k miles. We were towing our trailer when suddenly we lurched during acceleration and got dash message about the Electric Throttle Control, the check engine light came on and we were in limp mode. Made it to a dealership 10 minutes up the highway, going about 45mph. Our codes were P016F and P0336. They replaced our fuel pressure regulator at no cost, saying it was covered under a recall warranty. But that didn't solve things. They said they'd need to pull the transmission and replace the tone ring, again covered under a recall warranty. We were able to pick up the truck and do some minimal in-town driving while waiting for the part (took a week). Before dropping the truck back off for the repair, we checked the codes again and this time saw P0336, P0087, P1292. Dealer is replacing the tone ring today. I asked if the other codes might need parts as well but my rep said the techs checked the codes but never said more to him, so I guess I'll find out if things are fully solved with the replacing of the tone ring. It's been a good truck for us (never has left us stranded, until this and thankfully it didn't totally die), but so many recalls, it never ends. With an 'older', out of warranty truck, we've paid more than expected annually on maintenance and repairs, so that has definitely been frustrating. Will try to come back in a few days and say if any another work was necessary to get going again.

How much have you spent outside of warranty? Everything you've listed has been covered under warranty.

Also curious what you mean by unexpectedly high maintenance costs? 100$ oil change at 9k interval, and a 40$ fuel filter ~annual? Differentials, and well that's all. Other than getting screwed with diesel prices the actual maintenance costs are at or below norm

Now that I'm outside of warranty, I like to look at the cost of ownership. I financially prepared myself for $250 per month to keep the 2015 on the road. So far, the cost of ownership has been $97 per month in 2021 and $49 per month in 2022. So far, the cost to keep the truck has been below my budget projections and well below the monthly cost to replace the truck with a new one.

Biodiesel, outside of the water pump all trucks will have suspension repairs. It's the Major engines costs that are coming will tip the scales, Heck gas vehicles at 100K $350.00 in new spark Plugs, run another 100K and replace again. One Injector cost $250.00 for the 3.0VM. Long term ownership is the problem just about when the DSL (VM3.0) should be paying back Dividends on the investment BOOM $4K+ in repairs, Or waiting months for replacement parts, I have customer with 2013 Ram 3500 6.7 Cummins/Aisin 880K miles on 3rd Turbo and 3rd CP3 ( Because of leaks) and 3rd set of Injectors, 3 EGR cleanings Still making the owner $$$$$ in commercial use with factory SCR and DEF system. I don't know of any VM3.0 Legal OEM with 350K miles even on the Road. Vern does not matter or count he's been deleted for Years.

Based on the title of this thread, I hope this is a good place for this question.

I had a new tone ring installed this Tuesday. My question is, does anyone know if the "new/replacement" tone ring is any different from the old? Has there been any discussion around this? Has RAM said anything about it?

Thanks

So we just get to sit tight and wonder everytime we start out somewhere if it is going to fail? What good is that?

My guess is they're not going to spend the $ for R/D for any type of Upgrade.

As TC said, it's the same. The ones that were failing came from a bad batch where apparently the adhesive was the problem. They could not identify the bad ones by VIN Number so they made the recall for the years that could have received the bad batch. Seem like the good ones are not failing so no need to redesign.

Affirmative, same shit, so every 115k give or take you'll have a failure and have to split the transmission

C"mon John...all years are failing. It's the same European BS....

TC,
You know a lot more about the Ecos than me so I trust what you say. Are all the other years failing at the same rate as the recall years? From what I've read about guys reporting failures they were usually in the recall years like jdn112011.

Just give it some time, and the numbers will prove me correct.

There are tone wheels with 400,000 miles with no issues. There are tone wheels that only lasted 70,000 miles. Clearly, there was a quality control issue (some good and some bad). I try not to worry about it too much. My next big trip will be 880 miles one way, and that's when I'll think more about it. Honestly, I think there's a higher engine failure rate than a tone wheel failure rate, lol.

Biodiesel, RPM, warping, Heat, vibrations, driving habits even the environment effects adhesives, So why use that design your going to have failures. and to top that transmission removal to replace a single part that should out live the engine by 10,000 years. If you removed a clog tone ring and hung it outside and returned 10,000 years later it would still be a clog tone ring, your adhesive (element) ring would be delaminated and laying on the ground.

When are you going to take off the blinders? Both you guys are awesome Members and citizens. and I aways enjoy our conversations because it's always just our views and if we lived in the same town, we would be having these discussions with Beer and Pizza. :)

C'mon you two show be 1 clog ring failure on the millions of vehicles with that style, Yes the hall effect sensor can fail but not the ring. collision or road damage don't count or poor installation.

Truck is a 2015 Eco diesel with a PPEI tune and full delete. I was coming out of Island Park, Idaho headed south toward home in eastern Idaho towing the camper and RZR in my usual train set up and my pickup just shut down, just barely got of the road. first thought was, it blew up at 120,000 miles. Could not really find anything wrong, no smoke, bad sounds or coolant or oil leaks. So I grabbed my Autel code reader and the code came up for crankshaft positioning sensor failure. long story short. there is a tone ring that is shaped like a shallow cup that fits between the flywheel and the crankshaft with a magnetic tape around the outside diameter that signals the positioning sensor. A piece of the tape about and 1/8 inch wide delaminated off the ring (plus there was cracks in the tape all the way around it), then struck the sensor and they were both wrecked. From FCA the sensor is $445.00 (PN# 68102341AA), the Ring is $150.00, dealer labor to pull the Transmission and install the parts is $950.00 dollars. You can do the math. But it runs now. The sensor from NAPA is $100.00.

I don't disagree there's a better design, but I do believe the factory part, when manufactured correctly, will last the life of the engine.

If we lived in the same town, I would probably have your shop install an oil by-pass system and fuel pressure sensor, then we can eat pizza. ;)

Man, I read thru this thread a couple weeks ago and thought,”Hope I’m in the clear…” just bought the truck a couple months ago with nearly 250k miles, all records and recalls taken care of except the newest one for injector pump. Yesterday I back out of the drive and shift to D and it lurches forward and flashes the message about the throttle control, pull up codes and it’s the CKP. It had the emissions recall done that should have flashed the PCM to read Camshaft readings and ignore the CKP, but it’s not doing that obviously. Gunna call the dealer today and see if it’s warranties 🤞🏼
