Any pros/cons to not having the sensor installed? My truck is 15 months with 3,200 miles, it has not done a regen or at least
I don't think it has. I drive a Powersrtoke for work, so I am all too familiar with that smelly event.
Since you monitor pretty closely, have you noted a particular highway speed / rpm that seems to generate the best conditions for passive regeneration to occur when operating the truck unloaded at highway speed?
I really appreciate that. This would track with what I’ve been seeing in my 2022 DRW HO. I have to keep in the fuel to see passive regen on the highway. I’m usually running 72-75 and that seems to be getting fairly good results, but that only seems to be the case since I switched fuel stations. Whatever fuel I was getting prior, it seemed like passive regeneration just didn’t happen unless I ran for over an hour at 72-75 and even then, we’re talking marginal decreases.Sorry, little late to answer this question.
Speed really varies, but what I have seen is that at 22+ mpg there isn't any passive regen, 18-22 mpg is more of a net neutral, and anything less than 18 mpg will have continious passive regen. Below 12 mpg and you're cleaning it failry quickly.
If I want to jump on the interstate and try to reduce the DPF gauge it takes 10-15 miles at 85 mph empty to reduce it.
I do get some passive regen at 35-45 mph, despite the mpgs, due to the extremely low rpms causing a higher EGT and thus a hotter DPF.
Sadly there is a lot of truth to that…:-/ Toyota builds a good product but I think Rams engineers are better than this and so are Cummins’.Toyota needs to come up with an HD.
Not sure. It could be coolant from a leaking EGR cooler or oil from a leaking turbo seal killing the DPF. Looks like it was diagnosed really fast though. Keep us updated.Not sure if this is related but my engine light came on at around 750 miles so I called the dealer right away. I was able to get the truck looked at today 1075 miles on and within 25 min or so they said I need a DPF. Is there a string of bad DPFs or luck of the draw?
There is no incentive for me to get this done.
Is your luck really that bad?
I had this issue. went in to get the recall, flashed my computer and told me I already had the sensor. I had to show them that it was in fact not installed. The dealer did not want me to drive the truck with the flash done and the sensor missing. They gave me a rental and somehow found a sensor within a couple of days. Did they do this to someone else to put you number two on the list? If not you should be number one.So I have a fun one with the recall. I went in for an oil change, grid heater relay, and the Particulate Matter Sensor recall on my 22. They did the oil change, and he flashed the computer for Y43 at the same time. Then he went to parts to find that they didn't have any of them in stock. Didn't tell me until I picked up the truck and had a CEL on, and I had to ask. "Lost communication with particulate matter sensor". I am at 8k miles, and haven't had a single issue. Since they did this, I have been getting the frequent regens, about 50 miles apart, I can watch the gauge climb until it regens. Made an appointment to get it installed because they had one, showed up, no sensor in stock. Finally got them to tell me this morning that it is on order, and it will be in "in a few weeks, you're number 2 on the list". I had a 1500 mile road trip planned, but not if my mileage is going to suck, we'll take the wife's car. I get 20 MPG, but only 16 when it is in a regen.
Does anyone have any idea if the missing sensor may cause the frequent regens, or did I just luck out and it started happening at the same time? Trying to decide if I need to involve @RamCares or give them one more chance.
I’m sorry. If it was me, I’d put half a bottle (13 oz) of Diesel Kleen Power Service and a full tank of fuel and run it 75-80 mph on the trip you had planned. The cruise probably won’t work with the CEL but I would try to make it passively regen. See if you can borrow a trailer with a heavy load and pull it. That will make it clean itself out.Usually, yes it is. It would be just my luck that it started at the same time by coincidence. But I do not pretend to be a mechanic, I only play one on TV. I am hoping that someday, I will get a PM Sensor, and all will be right in my world.
Not a bad idea. I have an 8K toy hauler, I could hook up and just drive for an afternoon.I’m sorry.
