    i got a 2011 670 with isx cummins and got engine fault code spn 5024 fml 10 which is after-treatment 1 intake gas nox sensor heater ratio abnormal rate of change. does anyone know where this sensor is located on the def system. dealer is telling me there are 3 but i think they may be thinking of the 3 temp sensors on the top (or maybe they are right for a change) ive tried google with no help or if anyone has the part number for it that would be a big help.

    In my 2010 and my last 780/ 08, nox sensor is located on exhaust pipe, just behind dpf, and is hooked to a module located
    inside the frame, right side ,above DPF. Expensive, aprox.500$
