This code means that the computer in your car is having trouble talking to the part that controls the power take-off (PTO), which is used to run extra equipment like a snowplow or a dump truck bed.
The P064B code is triggered when the vehicle's main computer (ECU) detects an issue with the PTO control module, which is responsible for managing the power take-off system.
The P064B code indicates a malfunction in the PTO (Power Take-Off) control module. This module is responsible for controlling the PTO system, which is used to operate auxiliary equipment. The issue could be due to a communication error, a faulty module, or wiring problems.

This code has been associated with vehicles that utilize PTO systems for auxiliary equipment, often in commercial or heavy-duty applications.
Moderate – While the vehicle may still operate, the auxiliary equipment may not function, which could affect work operations.
Operating a vehicle with a malfunctioning PTO system can be unsafe, especially if the equipment is used for critical tasks.
• Vehicle in park or neutral
• Auxiliary equipment engaged
The PTO control module is typically located near the transmission or in the engine compartment.
Q: What is a PTO system?
A: A PTO system allows a vehicle to use engine power to operate auxiliary equipment, like a snowplow or a dump truck bed.
Q: Can I drive with a P064B code?
A: Yes, but the auxiliary equipment may not work. It's best to have it checked soon.
