What P200D means
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.
P200D at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor1 to 6 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P200D
- Malfunction indicator lamp on
- Regeneration stopped
- Power may be limited
Common causes of P200D
- Most likelyBank 2 filter overloaded with soot before regeneration
- PossibleLeaking injector or excess fuel on bank 2 cylinders
- Less likelyExhaust temperature sensor on bank 2 reading too high
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P200D means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 0 | Area: fuel and air metering and auxiliary emission controls. |
| 0D | The exact fault in that area. |
What to do next
- Note P200D and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P200D
What does P200D mean?
P200D means "Particulate Filter Over Temperature (Bank 2)". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P200D?
Drive gently and only to a workshop. With P200D the car can go into limp mode (reduced power) to protect itself.
Will P200D fail an emissions test?
Yes, it can. P200D is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P200D to fix?
Difficulty: hard. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will P200D clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
