If the harness tests good then replace the Nox Sensor and run a regen and see if the fault goes away
Hi, I just logged in. I help on here as I am able in between jobs. See PDF page 175 in the link I posted. for a picture of your Nox sensors. There is inlet and outlet #1 is inlet between the turbo and DPF. If you have a pyrometer right at the turbo elbow dont confuse that with the Nox sensor. the picture will show you what you are looking for. Let me know if you need more help.
