    Check engine light with some codes

    I started the truck today, no issues with temp about 10 deg.

    When I arrived at the store and shut it down. no issues.

    When I started the truck back up I got a check engine light and went home to see what codes I have.

    See pic below. I was unable to clear the codes.

    No messages on the dash. Just the CEL.

    It feels like the truck derated some power, but I could be wrong.

    I wont be able to get it into a dealer till Wednesday when I'm off from work.

    Are these codes going to cause me issues?

    If so I will take Monday off and take it to the dealer.

    I would check and clean the DPF exhaust wire connectors previously disconnected.

    Sounds to me like open connectors may be contaminated.

    I never disconnected any DPF wiring on this truck.

    Just picked it up last week from the dealer.

    It did go through an active Regen yesterday while driving with no issues.

    Ill look under there to see if anything is weird.

    I checked the wiring to the DPF. Everything looks good. I did not unplug anything. Way too cold for me to be messing with anything under there right now. I will look at that tomorrow. I did find this 4 position knob under the dash next to the OBDII port. I trace the wiring to the engine compartment and it goes to a connector that just hanging lose. Long wire too. Too long to be whats left from a programmer, it could go to the grill. I looked for any signs of DPF/DEF removal that would indicate the prior owner deleted and found none. No tool marks on exhaust system anywhere to suggest any removal/reinstallation was done. So that knob is some factory thing or something else.

    I did put my MM3 on it to read the codes and tried to clear them, but the MM3 came back with an error and would not clear the codes.

    Anchorage, a little warmer than Fairbanks. Could be the MM3 has to be VIN linked to clear codes.

    I would leave the codes in for your visit on Wednesday.

    Probably just a bad sensor, please keep us posted.
