Loss of power, misfiring, then dpf full

There’s a differential pressure sensor at the dpf too.

 

When was last time you removed and had DPF and DOC cleaned? Also, last time air management system service? How up to date is engine and after treatment software?

 

Whoa!!!! Talk about long regens!!! What's going on with your truck now?

 

If derates and have to move it off the road ,you can unplug speed sensor from the back of transmission ; your speedometer won't show speed but you can download gps speed app on phone.
The dpf could be clogge or the differential pressure sensor that gives bad reading, the one with 2 tubes thst goes in Dpf filter or check the harness.

 

Won't work on a MX powered truck. Vehicle speed is from ABS, not trans output speed sensor.
