I got a check engine light I few months back and decided to finally do something about it...
So there was a lot of errors, but I have pinned it down to something with the DPF. The sensors in general are giving me good readings, but the EGT (Exhaust gas temp) before SCR CAT is reading 21° should be 2-400°
So I want to start by fixing that, but which sensor is it? There are so many.... Am I correct in assuming it is #2 in
the attached parts diagram or is it integrated in the DPF sensor as some state?
Or am I completely lost here?
