You most likely have a wiring issue to your DPF pressure sensor. Start with thorough visual inspection of wiring from the EAS to the sensor for rubs or breaks/ green corroded wires.
I checked the wiring everything looks good and I unplugged some of the connectors they were very clean on the inside. The short wire loom is clean on all connections and I tested it with multimeter, it works good.
