P200D: Particulate Filter Over Temperature (Bank 2)
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.
What P200D means
P200D is a generic OBD-II powertrain code in the emissions group. Bank 2 is the side of a V or flat engine opposite cylinder 1.

Symptoms
- Check engine light or DPF warning light on
- Power loss / limp mode
- Increased fuel consumption
- Failed forced regeneration attempts
Common causes
- 01Runaway regenerationMost likely
Can I drive with P200D?
No. Stop and let the engine cool.
If the temperature gauge is high or you see steam, pull over and switch off. Driving an overheating engine can warp the head and blow the head gasket.
Why we rate it urgent
- Engine over-temperature can cause head-gasket and engine damage
- Turns on the check engine light
- Emissions-related: will usually fail an OBD inspection
Severity is our rule-based rating from the code’s flags in OBDex and the system it affects, not an inspection of your car. If the check engine light is flashing, or you notice overheating, low oil pressure, or brake or steering problems, stop driving and get help.
How to diagnose P200D
- 1
Confirm the code and save freeze-frame data
Read the codes with an OBD-II scan tool and note every code, not just P200D. Save the freeze-frame data (speed, load, temperature when the fault set) before clearing anything; it tells you when the fault happens.
- 2
Check for related codes first
Look for P200C. Related codes often share a cause; a circuit or sensor code usually needs fixing before a performance code like this one.
- 3
Check live data
Watch the related sensor and actuator readings in live data (Diesel particulate filter, DPF temperature sensor) and compare them with expected values in the service information for your vehicle.
- 4
Test the likely causes in order
Start with the most likely cause and work down: Runaway regeneration. Test before replacing parts.
- 5
Check for recalls and service bulletins
Look up recalls for your exact vehicle with its VIN, and ask a dealer about technical service bulletins (TSBs). Manufacturers sometimes issue software updates or extended warranties for known faults.
- 6
Clear the code and verify the repair
After the repair, clear the code and drive the car under the conditions in the freeze-frame data to confirm it does not return.

P200D FAQ
What does P200D mean?
P200D means “Particulate Filter Over Temperature (Bank 2)”. 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.
Is P200D serious? Can I keep driving?
We rate P200D as urgent severity. No. Stop and let the engine cool. If the temperature gauge is high or you see steam, pull over and switch off. Driving an overheating engine can warp the head and blow the head gasket.
What causes P200D?
The most common causes, from most to least likely: Runaway regeneration. Test before replacing parts, because several causes can set the same code.
How much does it cost to fix P200D?
Typical labor is about $190–$1,000 at an assumed $125/hour shop rate, plus parts. That is an estimate, not a quote: labor times and rates vary by vehicle and region, and diagnosis may be billed separately.
Can I fix P200D myself?
DIY difficulty is hard. Most owners leave this to a shop because it needs involved testing or specialist tools. Always confirm the cause before buying parts.
Will P200D clear itself?
If the fault was intermittent, the warning may go off once the computer stops seeing it, but the code stays in memory. Fix the cause; clearing the code alone doesn’t repair anything.
