I haven't did region yet it was late when I got done. Question is it would not get hot enough to do a regen injectors were replaced. Is that the problem or do I need to look further? Soot level shows a 5 Do I need to go ahead and pull filter and clean? and I'm being told you can wash them out rather than baking or do I buy a new one. Cummins History shows DPF filter 6/13 but no mileage or what was actually done. I know nothing about the truck other than the desk shows 808000 miles and 25000 hrs. Trying to get it on the road. Thanks in advance

Aftertreatment Fuel Pressure Sensor - Data Erratic, Intermittent, or Incorrect. The ECM has detected that the aftertreatment fuel pressure signal is not changing with engine operating conditions.


I.E.> It is "stuck in range", reading a valid pressure, but not changing in reading/pressure in sync with the rest of the engine.

-- You need to fix the problem with the Doser fuel pressure sensor.

The engine is not going to complete a regen until you fix this.
