  • The truck was diagnosed in this video is Freightliner Cascadia DD15 with one box. The nox sensor fault codes mentioned in this video are:
    ►SPN 3216 - FMI 14: NOx raw sensor does not support self diagnosis
    ► SPN 3057 - FMI 2: SCR outlet NOx sensor - Error
    ► SPN 520355 - FMI 14: NOx out sensor does not support self diagnosis
    A nitrogen oxide sensor or NOx sensor is typically a high-temperature device built to detect nitrogen oxides in combustion environments such as an automobile, truck tailpipe or smokestack.
    The term NOx represents several forms of nitrogen oxides such as NO (nitric oxide), NO2 (nitrogen dioxide) and N2O (nitrous oxide, also known as laughing gas). In a gasoline engine, NO is the most common form of NOx at around 93%, while NO2 is around 5% and the rest is N2O. There are other forms of NOx such as N2O4 (the dimer of NO2), which only exists at lower temperatures, and N2O5, for example.

    Thank you for this video and your time. I always appreciate your videos, as I learn from every one. It is especially helpful to me because I use a Snap On ProLink Edge too. I just had a DD13 the other day with similar codes. I R&R the Nox inlet sensor and ran a regen. Everything is good. Normally, when I get Nox related codes I do a regen just to watch and see what the PPM measure is and to see if they read “stable” or not, for conformation. Thanks again. 👍🏻

    • @truckingandfixing
      @truckingandfixing  Рік тому +1

      You are welcome! I do the same, regen every time after working on emission stuff. 👍

    • @TWR358
      @TWR358 Рік тому +1

      For me and the fleet I maintain, Which are anywhere from 200k-900k mile tractors, after a PM and a regen I see around 100-125ppm on the inlet side and around 5-15ppm on the outlet side. Hope this helps.

    Hi, I have a question. I got 2020 freitliner cascadia dd15
    Just changed nox out sensor
    I got readings
    nox inlet value average of 410ppm
    Outlet nox value average 257 ppm
    Different between sensors 157ppm
    Nox concentration sensors values inconsistent
    Does this mean I need to change the inlet also, or is something else wrong,

    What a scam OMG , I bought a 2020 cascadia and was in the shop twice in 3 months and one of the reasons was the nox sensor put my truck in limpmode forcing a tow to the dealership , Do not buy I repeat do not buy cascadias with x15 cummings way too many issues with sensora faults and bad weak ass Modulate. These new trucks are a complete scam.
