This guide shows how to perform DPF static regeneration and reset learned values on a Ford Transit 2.0 diesel using an OBD2 scanner.
Understanding DPF soot values (important)
From my live data logs:
- Closed loop soot (%): 27%
- Open loop soot (%): 59%
What it means:
- Closed loop (accurate)
→ Based on differential pressure sensor + feedback
→ This is the real soot load - Open loop (estimated)
→ Calculated from driving conditions (fuel, time, load)
→ Used when sensors are unreliable or as backup
👉 During regen you will see both values decreasing.
After successful regen:
- Closed loop: ~1%
- Open loop: ~3%
This matches my result → regen successful

Technical overview
| Vehicle | Ford Transit |
|---|---|
| Year | 2020 |
| System | Engine / DPF |
| Procedure type | Service regeneration + reset |
| Difficulty | Medium |
| Time required | ~30–40 minutes |
| Prerequisites | Warm engine, safe environment |
Step-by-step procedure
Read fault codes
- Connect scanner → Engine (PCM)
- Confirm code:
- P2002 – DPF efficiency below threshold
Check live data
Go to:
Live Data → DPF parameters
Check:
- Soot load (%)
- EGT sensors
- Coolant temp
Warm up the engine
If engine is cold:
- Drive ~2–5 minutes
- Reach at least:
- ECT ≥ 65°C
Verify regeneration conditions
Before starting regen:
- Engine coolant temp: 65–105°C
- EGT: ~150–800°C (initial ~165°C OK)
- Engine speed: Idle
- Vehicle speed: < 1 km/h (stationary)
Start DPF static regeneration
Go to:
Service / Hot functions → DPF regeneration
Confirm warnings:
- Exhaust temps up to 600°C
- Engine RPM will increase
- Duration up to 40 minutes
Press OK / Continue
Monitor regeneration
During regen:
- RPM increases automatically
- EGT rises significantly
- Soot values decrease
Expected outcome:
- Closed loop → ~1%
- Open loop → ~3%
⏱️ Your case: ~30 minutes → correct
Reset learned values
After regen:
Go to:
Reset → Particulate Filter Learned Values
Run procedure → wait until complete
👉 This step is important after heavy clogging or faults
Clear fault codes
- Clear all DTCs
- Re-check:
- No active DPF codes
- Values stable
Additional information & compatibility notes
If regen fails:
- Check differential pressure sensor
- Check EGT sensors
- Check for exhaust leaks
High open loop vs low closed loop mismatch can indicate:
- Bad driving pattern
- Incorrect previous regen
P2002 often triggered by:
- Short trips
- Incomplete regen cycles
