PTO Control Actuator Supply Voltage
The control module detected low voltage at the PTO actuator.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The Power Take-Off (PTO) actuator isn’t getting enough voltage to work properly, which might cause issues with any attached equipment that relies on it.
What the computer is actually seeing
The computer sees a supply voltage to the PTO actuator of less than 8 volts when it expects it to be above that, typically around 10-14 volts when the engine is operating.
What a healthy reading looks like
Expected voltage supply to the PTO actuator is between 10-14 volts for normal operation.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Check the connector and wiring to the PTO actuator for damage or corrosion. Decision: Is the wiring intact? Yes: Go to step 2. No: Repair or replace the damaged wiring/connector.
- 22. Measure the voltage at the PTO actuator with the engine running. Decision: Is the voltage between 10-14 volts? Yes: Replace the PTO actuator. No: Go to step 3.
- 33. Check the ground connections for the PTO system. Decision: Are the grounds secure and clean? Yes: Check the control module. No: Clean and secure the grounds.
Common causes
- Damaged wiring or connectors leading to the PTO actuator.
- A faulty PTO actuator that draws too much current and causes voltage drop.
- Faulty control module or ground connections affecting voltage supply.

Frequently asked questions
Is it safe to drive with this code?
It's moderate severity; the equipment connected to the PTO might not function properly, which could affect your work.
Will this code come back after clearing?
If the underlying issue isn’t fixed, it will likely return once the vehicle operates again.
Why does this code often pair with SPN 4314?
Both codes are related to issues in the PTO system, often stemming from similar electrical faults.
