P260E: Particulate Filter Regeneration Lamp Control Circuit
The DPF regeneration warning lamp circuit is faulty. The driver may not be alerted to a required highway run that supports passive regeneration.
What P260E means
P260E is a generic OBD-II powertrain code in the emissions group. In plain English: the computer found an electrical fault in that circuit: an open, short or bad connection, or a failed component.

Symptoms
- Check engine light or DPF warning light on
- Power loss / limp mode
- Increased fuel consumption
- Failed forced regeneration attempts
Common causes
- 01Burnt-out indicator bulbMost likely
- 02Open or shorted wire to the clusterPossible
Can I drive with P260E?
Usually yes, for a short time.
The car will often drive normally, but get it diagnosed soon. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
Why we rate it moderate
- Turns on the check engine light
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 P260E
- 1
Confirm the code and save freeze-frame data
Read the codes with an OBD-II scan tool and note every code, not just P260E. Save the freeze-frame data (speed, load, temperature when the fault set) before clearing anything; it tells you when the fault happens.
- 2
Fix other faults first
If other codes are stored, start with power-supply, sensor-circuit and communication codes. They can cause this code as a side effect.
- 3
Test the circuit
Inspect the wiring and connector at the dpf regen lamp and instrument cluster for damage, corrosion or chafing. With a multimeter, check supply voltage, ground and signal against the specifications in the service manual for your vehicle.
- 4
Test the likely causes in order
Start with the most likely cause and work down: Burnt-out indicator bulb; open or shorted wire to the cluster. 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.

P260E FAQ
What does P260E mean?
P260E means “Particulate Filter Regeneration Lamp Control Circuit”. The DPF regeneration warning lamp circuit is faulty. The driver may not be alerted to a required highway run that supports passive regeneration.
Is P260E serious? Can I keep driving?
We rate P260E as moderate severity. Usually yes, for a short time. The car will often drive normally, but get it diagnosed soon. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
What causes P260E?
The most common causes, from most to least likely: Burnt-out indicator bulb; Open or shorted wire to the cluster. Test before replacing parts, because several causes can set the same code.
How much does it cost to fix P260E?
Typical labor is about $25–$125 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 P260E myself?
DIY difficulty is easy. Many owners can handle it with a scan tool, a multimeter and basic hand tools. Always confirm the cause before buying parts.
Will P260E 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.
