P200D: Particulate Filter Over Temperature (Bank 2)
Standardized SAE J2012 code · P20xx — Fuel & air metering and auxiliary emission controls
What does P200D mean?
A temperature sensor at the diesel particulate filter (DPF) on bank 2 has exceeded the safe limit — typically during a runaway regeneration. Continued operation can melt or crack the substrate.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Symptoms
- Check engine light or DPF warning light on
- Power loss / limp mode
- Increased fuel consumption
- Failed forced regeneration attempts
Common causes
- High Runaway regeneration
