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.

Sintomi comuni

  • Severe derate
  • DPF replacement likely

Cause tipiche

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

Di quale scanner hai bisogno?

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

Usa dati live e freeze frame prima di sostituire componenti. I codici ABS, SRS e U richiedono di solito uno scanner full-system.

Consigli diagnostici

  • Registra il freeze frame quando compare il codice
  • Cancella il codice solo dopo aver risolto la causa
  • Controlla codici pending correlati
  • Verifica che la batteria sia sopra 12,4 V prima di sospettare i sensori
