Technical Description of OBD-II Trouble Code
PTO Control Circuit /Open
What is the meaning of this code?
This code is a generic powertrain diagnostic trouble code (DTC) that is applicable to many OBD-II vehicles (1996-newer). This includes vehicles from Ford, GMC, Chevy, Dodge, Ram, and others. Although it is a generic code, the specific repair steps may vary depending on the year, make, model, and powertrain configuration of the vehicle.
OBD-II trouble code P260A and related codes P260B, P260C, and P260D are associated with the PTO or power take off control circuit.
The PTO or power take-off is a system that is connected to the vehicle’s transmission and is used to operate auxiliary equipment such as a winch, snow plow, or dump bed.
When the PCM detects improper voltage or resistance in the PTO control circuit, code P260A will be triggered and the check engine light, service engine soon light, or both may illuminate.
What is the severity of this DTC?
This code is generally not severe as it mainly affects the functionality of the PTO equipment and not the regular vehicle functions.
What are some of the symptoms of the code?
Symptoms of a P260A trouble code may include:
What are some of the common causes of the code?
Possible causes for this P260A code may include:
What are some P260A troubleshooting steps?
The first step in troubleshooting any malfunction is to research the Technical Service Bulletins (TSB’s) specific to the vehicle’s year, model, and engine/transmission configuration. This can save time by providing guidance in the right direction.
The second step is to inspect all components associated with the PTO power take-off circuit for any obvious physical damage. Conduct a thorough visual inspection of the wiring for defects such as scraping, rubbing, bare wires, or burn spots. Check the connectors and connections for security, corrosion, and damaged pins. This includes all wiring connectors and connections to all components, including the PCM. Refer to the vehicle’s specific technical data to verify the configuration of the oil level safety circuit and determine if a fuse or fuse-able link is part of the circuit.
Advanced Steps
The advanced steps are highly vehicle-specific and require specialized equipment for accurate execution. These procedures involve using a digital multimeter and referencing the vehicle’s specific technical resources. In this situation, an oil pressure gauge may aid in the troubleshooting process.
This article is purely informational, and the vehicle’s specific technical data and service bulletins should always take precedence.
