    I am wondering what I should see for exhaust temp during a parked regen.

    The target temperature inside the dpf for proper conversion of soot to ash is around 1050*F. I would say anything exceeding plus or minus 150* or so from this number in a regen log from this temp should be looked into as a potential problem.

    I am doing a park regen right now, my temperature went up to about 200degrees. After it stopped my truck requested another park regen.

    If you’re needing that many regens, you may need a new filter or perhaps a sensor. You should go see your truck manufacturer.

    I should add that 200° is normal temp for your dash to show. Mine goes up to about 225° before the fan kicks in and brings it back down to 200°. But unless you’re interrupting your parked regen, you should never need 2 in a row.

    I find it awfully hard to believe your exhaust temp is only 200 degrees during a regen. Are you mistakenly looking at coolant temp rather than exhaust temp?
     
    Joshuld and Socal Xpress Thank this.
