2022 Ecodiesel, 33k miles. i got the P2002 DTC.. i understand that this is a soft code that may clear itself.. so do i need to get out on the hiway and hope for regen? the truck has been used for mainly short trips lately, so i suspect i'm at that magic 80%? I have never seen any messages on the dash about servicing dpf system or regen in progress or anything like that.. in y'alls experience, will a nice long hi speed trip on the hiway help clear this? thanks for any info..
