P200D Particulate Filter Over Temperature (Bank 2)

Check engine lightOn
EmissionsRelevant
Drive cycleNot required

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.

Likely causes

Bank 2 filter overloaded with soot before regeneration
Leaking injector or excess fuel on bank 2 cylinders
Exhaust temperature sensor on bank 2 reading too high

Symptoms

  • Malfunction indicator lamp on
  • Regeneration stopped
  • Power may be limited
