Hey guys. I'd like to introduce myself. I'm Paul from Portland Victoria.
So.. I just bought my first Navara. 2011 D40. YD25.
This thing's had a pretty hard life and has spent most of its time near the beach. Problem I have it's throwing a P0473 fault code which is the dpf differential pressure sensor circuit high. I've back probed all of the three terminals and can't find a ground signal. I've also repaired a load of wiring underneath that was melted behind the dpf. The wiring I repaired is for the O2 sensor and the rear EGT sensor. The question I have is should I have a ground at the differential pressure sensor? And what pin should it be. I have grey wire, a blue wire and a green with white trace. Does anyone have a pcm wiring diagram? Is it possible that the pcm could be at fault here? Thanks in advance for your help.
