PTO Control Circuit / Open
The P260A code indicates that the Powertrain Control Module (PCM) has detected an open circuit in the Power Take-Off (PTO) control circuit. This typically means there is a break in the wiring or a faulty component in the PTO system, preventing proper operation of the PTO unit.
01. Most Common Causes
- Open or shorted wiring in the PTO control circuit
- Faulty PTO switch or relay
- Blown fuse in the PTO circuit
- Faulty PCM (rare)
02. Symptoms You Will Notice
- PTO inoperative or fails to engage/disengage
- Check Engine Light illuminated
- Possible drivability issues if PTO is used for vehicle functions
03. Step-by-Step Diagnosis
Step 1: Use a scan tool to verify the code and check for related codes.
Step 2: Inspect the PTO fuse and replace if blown.
Step 3: Visually inspect wiring and connectors for damage, corrosion, or loose connections.
Step 4: Test the PTO switch and relay for proper operation using a multimeter.
Step 5: Check continuity in the control circuit from the PCM to the PTO solenoid.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It depends. If the PTO is not needed for vehicle operation, you can drive short distances, but the underlying issue should be repaired promptly to avoid potential electrical problems.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for diagnosis and repair, but it can be higher if the PCM needs replacement or if extensive wiring repair is required.
