PTO Engaged Lamp Control Circuit Malfunction

📅 Last reviewed: July 2026
What does the P260D code mean?

The P260D code indicates a fault 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 proper voltage and resistance. A malfunction can be due to a blown bulb, faulty wiring, a defective PTO switch, or a PCM issue. This code is common in vehicles equipped with PTO systems, such as trucks and commercial vehicles.
