38ryr88 Posted October 17, 2010 Share Posted October 17, 2010 Had my first 6.7 that was in for a stalling concern. Dtc's were p0606,p06a6,p2138,p0336,p0193,p02e1. If you suspect a v-ref short and find no chafe at the egr cooler gasket, closely inspect the plug at the dpf pressure sensor. I found a tiny chafe on the v-ref wire and the signal return wire. Weird thing is that the chafe point is about 1 inch away from the sensor bracket. I had to remove the tab on the wire harness to to get enough play to ground out the wire and duplicate the stall ? I hope this info may save someone some time as we have yet to recieve our printed EVTM's. It took forever to pull up all the v-ref circuits in the online wiring diagrams.
