PTO Control Circuit High Voltage
The P260C code indicates that the Powertrain Control Module (PCM) has detected a high voltage condition in the Power Take-Off (PTO) control circuit. This circuit is responsible for engaging and disengaging the PTO, which powers auxiliary equipment like hydraulic pumps or generators. A high voltage reading typically points to a short to power, a faulty PTO solenoid, or a wiring issue. This can prevent the PTO from operating correctly, affecting vehicle functionality.
01. Most Common Causes
- Short to power in the PTO control circuit wiring
- Faulty PTO solenoid or relay
- Damaged PCM or internal short
02. Symptoms You Will Notice
- PTO fails to engage or disengage
- Check Engine Light illuminated
- Auxiliary equipment not operating
03. Step-by-Step Diagnosis
Step 1: Use a scan tool to retrieve the code and check for related codes.
Step 2: Visually inspect the PTO wiring and connectors for damage, corrosion, or shorts.
Step 3: Test the PTO solenoid resistance with a multimeter; compare to specifications.
Step 4: Check for voltage at the PTO control circuit with the ignition on; should be within spec.
Step 5: If wiring and solenoid are okay, test the PCM output or replace the PCM.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It may be safe to drive, but the PTO will likely not function, and the Check Engine Light will stay on. Have it diagnosed soon to avoid further issues.
How much does it cost to fix?▼
Repair costs typically range from $50 to $150 for parts like a solenoid or relay, plus diagnostic time. Labor can add $100-$200 depending on the shop.
