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 and do not automatically mean the DOC must be replaced. Diagnose the complete engine, fuel, turbocharger, sensor and exhaust aftertreatment systems before replacing the DOC.
