P200C Particulate Filter Over Temperature (Bank 1)
A temperature sensor at the diesel particulate filter (DPF) on bank 1 has exceeded the safe limit — typically during a runaway regeneration. Continued operation can melt or crack the substrate.
Is it safe to drive with P200C?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
Common causes
- Most likelyExcessive soot load triggers runaway regeneration
- PossiblePost-injection over-fueling during regeneration
- Less likelyDPF temperature sensor reading drifts high
Symptoms
- Check engine light or DPF warning light on
- Power loss / limp mode
- Increased fuel consumption
- Failed forced regeneration attempts
