Common Symptoms
- Frequent passive regen never completes (short-duty tractors)
- DPF lamp + derate on soot load > 100%

- Differential pressure sensor hose plugged / cracked Likely
- Ash loaded beyond service interval (5,000+ hrs) Likely

Step-by-Step Diagnostic Procedure
Record DPF ΔP and soot load in Service ADVISOR at rated load.
Command parked regen and monitor DPF inlet temperature ramp.
Clean DPF differential pressure sensor hoses (common on compact tractors).
If ash load > 95%, remove and send out for ash cleaning.
