@@user-qi5vc3bk7e I’ve never had that code pop up for a semi truck. Is there a code number?

@@alreyindustries this is exactly what it stats. Driving me crazy because I can’t find anything that would tell me which sensor that is. I changed the sensor between the DOC and the PDF. No change. Same reading. -459 F SPN: 3249 The reading from the exhaust temperature sensor located midstream of the other two temperature sensors in the aftertreatment system in exhaust bank 1.

@@user-qi5vc3bk7e hm sounds strange. What you could do is turn the key on and then unplug 1 temp sensor at a time. Check the codes after you unplug one and see if the code changes or what other code pops up. When you get the right temp sensor it will either not throw a new code or give you the same temp sensor number with a different fault.

Every one box that I have replaced comes with nothing. No dpfs, no sensors, no heat shield, nothing but the scr and docs which are one piece with the box. That’s really what you’re paying for. Those two components and then the rest of the box is just a frame or shell that everything else attaches to.

What is address ?1.1 is ok my friend paid 26000 for replace

@@thisiskingone I'm based in Jacksonville,FL and go to the Freightliner shop here. If your shop is honest with you they can usually save a few sensors and if your like me and recently replaced your DPF Filters then you can use the same ones . Long story short they used my old nox sensors and Filters and I paid $12k. If I would have went with new everything I would have paid a little over $15k.

😂😂😂

Lol. Nobody has time for that 😂

Yea I think I said in the video that I might have those mixed up but you can tell the difference by the size of the sensor head

Sorry it’s not giving me the option to translate. I don’t understand.

Hm, I didn’t even notice that when I made the video. This must be a ghg17 one box or newer. The older one boxes have the outlet tube and sensor right after the dpfs right there on top of the one box.

Yes same question. I haven’t read in dtna portal if they did away with dpf outlet pressure. Maybe they did? Using doc inlet pressure for finding doc face plugging, and using the new soot sensor as a monitor for plugged dpf? I dunno, that’s confusing to me hahha

dd15troubleshooting.com/all-1-box-sensor-locations/ On that website there are picture diagrams that you can zoom in on and look at. If you look at the epa 10 one box it is number 17. If you look at the epa 14 one box it is number 16. The one box in my video doesn’t have an outlet DPF pressure sensor only an inlet.

@@alreyindustries yeah i had one in a 2016 cascadia with no outlet, i thought i was going crazy because it had the 3251 code and i needed to know why it had zero voltage

Dpf outlet is the exact same as your SCR inlet. It would read the same pressure
