PTO Engaged Lamp Control Circuit Malfunction
The P260D code indicates a problem in the circuit that controls the Power Take-Off (PTO) engaged lamp. This lamp illuminates on the dashboard when the PTO is active. The Powertrain Control Module (PCM) monitors the circuit for electrical faults such as shorts, opens, or excessive resistance. When the expected voltage or current is not detected, the code is set. Common causes include a faulty PTO engaged lamp bulb, damaged wiring or connectors, a blown fuse, or a defective PCM. The issue is typically electrical and does not directly affect engine performance but may prevent the driver from knowing the PTO status.
01. Most Common Causes
- Faulty PTO engaged lamp bulb
- Damaged wiring or connectors in the lamp circuit
- Blown fuse for the PTO lamp circuit
- Defective PCM
02. Symptoms You Will Notice
- PTO engaged lamp does not illuminate when PTO is active
- PTO engaged lamp stays on continuously
- Check Engine Light illuminated
03. Step-by-Step Diagnosis
Step 1: Visually inspect the PTO engaged lamp bulb and replace if burned out.
Step 2: Check the fuse for the PTO lamp circuit and replace if blown.
Step 3: Inspect wiring and connectors for damage, corrosion, or loose connections; repair as needed.
Step 4: If all else is fine, test the circuit with a multimeter to verify continuity and voltage; if no issues found, suspect a faulty PCM and consult a professional.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
Yes, it is generally safe to drive because the code only affects the PTO engaged lamp. However, you may not know when the PTO is engaged, which could lead to unintended operation or damage if the PTO is left on.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150, including parts and labor. Replacing a bulb or fuse is inexpensive, while wiring repairs may cost more.
