Diesel Particulate Filter Efficiency Below Threshold Bank 1

on 2014 Ram 2500 6.7L I6 Cummins Diesel · 4WD

What this code means

The DPF on bank 1 is not filtering soot effectively. Differential pressure across the filter is abnormal.

Symptoms

  • Check engine light
  • DPF warning light
  • Reduced power
  • Excessive black smoke

Common causes

  • Clogged/damaged DPF
  • Failed differential pressure sensor
  • Faulty DPF temperature sensor
  • Oil contamination of DPF

Diagnostic steps

  1. Check DPF differential pressure
  2. Inspect temperature sensors
  3. Attempt forced regeneration
  4. Check soot loading percentage

Repair notes

Attempt forced regeneration first. If soot load exceeds limit, professional cleaning or DPF replacement required.
