Evening all, I have a D6T (SLJ00192) that popped up a fault code of EGR Diff Pressure Low, E1093-1. Ive never come across an EGR with pressure sensors before and don't have access to SIS or ET, yet. Is this just a sign of the EGR being block or something else, also from memory the EGR valve looked fairly buried, is it a bit of a pain to sort out? Machine has 6915 hours on it TIA
If you remove the floor board, the EGR delta sensor is accessible at the rear of the engine. You can remove the venturi manifold and make sure the holes are not plugged with soot. Remove delta sensor and blow the holes out with compressed air to ensure they are clear. That is where I would start.
