    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.

    Yes, the little harness to just the delta P sensor rubs wires bad. I keep that short harness in stock in our parts room.

    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.
    Where is the eas located?
