This code means that there's a problem with the light that tells you when a special tool on a truck, called a PTO, is turned on. It's like if a light on your toy stopped working and you couldn't tell if it was on or off.
The code P260D indicates a malfunction in the circuit that controls the Power Take-Off (PTO) engaged indicator lamp.
The Power Take-Off (PTO) system is used to transfer power from the engine to auxiliary equipment. The PTO engaged lamp is an indicator on the dashboard that lights up when the PTO is activated. Code P260D is triggered when the Engine Control Module (ECM) detects an issue with the electrical circuit that controls this lamp, such as an open or short circuit.
• PTO engaged lamp not illuminating
• PTO system not functioning properly
• Check engine light may be on
• Faulty PTO engaged lamp
• Open or short circuit in the PTO lamp wiring
• Defective ECM or control module
PTO: Power Take-Off
ECM: Engine Control Module
• Check the PTO engaged lamp for proper operation.
• Inspect the wiring and connectors for damage or corrosion.
• Test the ECM for proper functionality.
• Replace the faulty PTO engaged lamp.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• Digital multimeter
• OBD-II scanner
• Screwdrivers

Moderate
• Ford F-Series
• Chevrolet Silverado
• Ram 1500
• Regularly inspect the PTO system and wiring.
• Ensure proper maintenance of the vehicle's electrical system.
• Avoid overloading the PTO system.
Electrical Circuit Issue
• Do not ignore the warning light if it doesn't turn on when expected.
• Consult a professional mechanic if you're unsure about the repairs.
Check with your vehicle manufacturer for warranty coverage on electrical components.
P260D is a relatively uncommon code, typically associated with vehicles equipped with PTO systems.
Moderate – While the vehicle may still be drivable, the PTO system may not function correctly, which could affect equipment operation.
Ensure all repairs are performed by a qualified technician to maintain vehicle safety and compliance with regulations.
• Vehicle parked with engine running.
• PTO system activated.
The PTO engaged lamp is located on the vehicle's dashboard, and its circuit runs through the vehicle's wiring harness to the ECM.
Q: What is a PTO?
A: PTO stands for Power Take-Off, a system that transfers engine power to auxiliary equipment.
Q: Can I drive with a P260D code?
A: Yes, but the PTO system may not work, which could affect equipment that relies on it.
