P200DParticulate Filter Over Temperature (Bank 2)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P200D is the overheating code for a particulate filter on bank 2 and therefore only appears where the exhaust of the second bank has its own filter and temperature sensors. No manufacturer documents P200D publicly; the published diesel layouts of GM, Ford and Hino run one filter and report its overheating as P200C. Those tables show how such a limit is built: a fixed ceiling between roughly 800 and 950 °C on the sensor ahead of or behind the filter, confirmed over many samples or a few seconds, and stored at once with the warning lamp. On a twin-filter engine the bank 2 check looks only at its own sensors, so a fault limited to one side, such as one leaking injector, an overloaded filter on that bank or a skewed sensor, separates the two codes. The control unit will usually stop regeneration and may limit power.
- What you may notice
- Malfunction indicator lamp on
- Regeneration stopped
- Power may be limited
- Likely causes
- LikelyBank 2 filter overloaded with soot before regeneration
- PossibleLeaking injector or excess fuel on bank 2 cylinders
- RareExhaust temperature sensor on bank 2 reading too high
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
