What are some of the symptoms of the code?
Symptoms of a P260C fault code may include:
- Auxiliary power take-off equipment will not operate
- Check engine light illuminated
What are some common causes of the code?
Causes
of this P260C code may include:
- Faulty PTO relay coil control
- Open or short circuit in the PTO control circuit
- Defective or damaged wiring
- Corroded, damaged, or loose connector
- Faulty fuse or fusible link (if applicable)
- Faulty PCM
What are the troubleshooting steps for P260C?
The first step in the troubleshooting process for any malfunction is to search for Technical Service Bulletins (TSBs) for the specific vehicle by year, model, and engine/transmission configuration. In some circumstances, this can save significant time in the long run by pointing you in the right direction.
The second step is to locate all components associated with the PTO power take-off circuit and look for obvious physical damage. Perform a thorough visual inspection to check that the associated wiring shows no obvious defects such as scraping, rubbing, exposed wires, or burn marks. Then, check connectors and connections for security, corrosion, and damaged pins. This process should include all wiring connectors and connections to all components, including the PCM. Consult vehicle-specific technical data to verify the oil level safety circuit configuration and see if a fuse or fusible link is incorporated in the circuit.
Advanced Steps
Advanced steps become very vehicle-specific and require appropriate advanced equipment to perform accurately. These procedures require a digital multimeter and vehicle-specific technical references. In this situation, an oil pressure gauge may facilitate the troubleshooting process.
