Got the dreaded check engine light and pulled codes to find P2002 as shown. Is this an easy fix or am I forced to deal with the idiots in the Ford service department?

If it were me, first thing I would do is a driveway regen using forscan. By the way, how full is the dpf?

I did that and then cleared the code. It looked like it was fixed buy it came back on the next afternoon again. The percentages were something like 7% and 58% for the two different loop systems.

Could be a clogged DPF that needs to be removed and cleaned/replaced - over time there is a small amount of ash that can't be removed from the filter by regen, if you have a lot of miles on it I would suspect this. Could also be a malfunctioning pressure sensor, or it could be an air leak upstream of the DPF leading to unexpected pressure differential readings. Alternatively could be a cracked or damaged DPF. If you've cleared the codes and gone through a couple regen cycles and it keeps coming back, you may need to have it inspected.

There is only 23,000 miles on the DPF. The manual regen blew a ton of smoke for several minutes which I'm unsure if that's normal or not... I am going to change the oil this weekend so I will check for any leaks or possible damage to components or wiring. Where is the pressure sensor located on these systems for bank 1? I am gonna guess the sensor is the problem but not sure yet.
