Signs Your DOC May Need Inspection or Replacement

  • Frequent, incomplete, or unsuccessful DPF regeneration cycles
  • DOC efficiency or catalyst-conversion diagnostic trouble codes
  • Slow exhaust-temperature increase during an active regeneration
  • Excessive soot, oil, fuel, or ash contamination on the catalyst face
  • High exhaust backpressure or abnormal pressure readings
  • Reduced engine performance under load
  • Cracking, melting, corrosion, or other physical catalyst damage

These symptoms may have multiple causes. Diagnose the complete engine, fuel, turbocharger, and exhaust aftertreatment systems before replacing the DOC.

*Note: Always verify exact compatibility using the vehicle VIN, emissions-family label, aftertreatment assembly information, and the original stamped OEM part number on the DOC before ordering.
