Diesel Particulate Filter Restriction — Ash Level Very High

Understand P2461, common causes, and the right TOPDON scanner to diagnose it.

Ash level very high in DPF — cleaning or replacement required.

Vanliga symptom

  • Severe derate
  • DPF replacement likely

Typiska orsaker

  • High-mileage DPF never cleaned
  • Excessive oil consumption
  • Wrong CJ-4 oil not used

Vilken scanner behöver du?

Full-system scanner (engine, ABS, SRS, transmission, service resets)

Använd live-data och freeze frame innan du byter delar. ABS-, SRS- och U-koder kräver oftast en fullsystems-scanner.

Diagnostiktips

  • Spara freeze frame när koden först sätts
  • Rensa koden först efter att orsaken är åtgärdad
  • Kontrollera relaterade väntande koder
  • Verifiera batterispänning över 12,4 V innan du misstänker sensorer
