P260D code meaning
PTO Engaged Lamp Control Circuit
What P260D means
P260D concerns the output that drives the lamp or LED telling the operator that the power take-off is engaged; the module has found a fault in that lamp circuit. For GM's heavy-duty pickup chassis cabs, upfitter bulletin UI 80c explains how such an indicator behaves: the LED in the PTO switch blinks quickly while the relay is energized, turns steady once load feedback confirms engagement or after 3 s without feedback, and blinks slowly when a memory speed is stored. A remote PTO indicator can be wired as well. GM's PTO code table does not list P260D, and no other maker documents it publicly. The PTO itself may work normally, but the operator loses the visual confirmation, which matters for safe work with tippers, cranes or pumps. P260A to P260C cover the control circuit itself.
P260D at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyEasy, DIY possible
- Typical labor0.3 to 1.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P260D
- PTO indicator stays dark or lit regardless of PTO state
- PTO itself works normally
Common causes of P260D
- Most likelyFailed indicator lamp or LED
- PossibleOpen or shorted wire to the indicator, often in add-on wiring
- Less likelyFault in the PTO switch assembly with integrated LED
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P260D means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 6 | Area: computer (engine control module) and output circuits. |
| 0D | The exact fault in that area. |
What to do next
- Note P260D 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 P260D
What does P260D mean?
P260D means "PTO Engaged Lamp Control Circuit". P260D concerns the output that drives the lamp or LED telling the operator that the power take-off is engaged; the module has found a fault in that lamp circuit. It is a generic code, so it means the same on every make.
Is it safe to drive with P260D?
P260D does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P260D fail an emissions test?
P260D is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P260D to fix?
Difficulty: easy. A typical repair takes 0.3 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P260D clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
