    I think your thermocoupler on your main output bearing may be going, just give a tug on the ole ducks nest handle and that might do er. If not get a henway

    2791 is the thermocoupler, but 1569 is the flux capacitor.
    3216 would be the blinker fluid sensor.

    These are things you need to address right away.
    If not you will be in danger of running too cold, having no turn signals or flashers, and no way to roll back time to meet a deadline.
     
    BostonTanker and kingwayde Thank this.

    2791 is for the EGR actuator
    1569 is engine protection torque derate
    3216 is for a Nox sensor
    So it looks like the EGR valve hung up, causing a bad reading on the Nox sensor which then resulted in the engine being derated.
    I had a truck that thru an EGR error, I took out the EGR valve and found that it had corrosion at the pivot point of the butterfly valve. I just shot it with some wd40 and it was good for about two weeks. Then I just replaced it for about $400

    I just came out of a 12, i could swear it tells you what the codes are.

    I'm in a 16 now. And it does.

    Once in a blue moon it tells me the fuel gauge. Which has been replaced twice already.
    It goes dead when climbing hills. Sometimes.
