Code P0658 Ford Description
The P0658 Ford diagnostic trouble code (DTC) refers to an issue with the Actuator Supply Voltage 'A' Circuit being detected as low. This code indicates that the voltage supplied to a specific actuator in the vehicle is not within the expected range. Actuators are components that convert electrical signals into mechanical actions, such as controlling the position of engine components, emission system elements, or other systems within the vehicle. In this case, the low voltage could be caused by a wiring issue, faulty actuator, or a problem with the power supply.
Common Causes of P0658 Ford
- Faulty actuator
- Wiring issue or short circuit in the actuator circuit
- Corrosion or poor connection in the wiring harness
- Defective power supply to the actuator
- Issues with the Engine Control Module (ECM) or related control modules
Symptoms of P0658 Ford
- Check Engine Light illuminated on the dashboard
- Reduced engine power or acceleration
- Rough idling or stalling
- Difficulty starting the vehicle
- Decreased fuel efficiency
How to Fix P0658 Ford
- Diagnose the specific actuator affected by the low voltage
- Inspect wiring harness and connectors for any damage or corrosion
- Test the power supply to the actuator and replace if necessary
- Check the actuator for proper operation and replace if found faulty
- Clear the code and perform a test drive to ensure the issue is resolved
Cost to Fix P0658 Ford

Frequently Asked Questions about P0658 Ford Code
1. What does the OBDII code P0658 mean on a Ford?
P0658 indicates that the Powertrain Control Module (PCM) has detected a low voltage condition in the Actuator Supply Voltage 'A' circuit.
2. What are the common symptoms of the P0658 code in a Ford vehicle?
Symptoms may include poor engine performance, failure of certain actuators or sensors to operate, illumination of the check engine light, and possibly entering limp mode.
3. What causes the P0658 code to appear on a Ford?
Common causes include a faulty actuator, damaged wiring or connectors, a short circuit, or a malfunctioning PCM.
4. How do I diagnose the P0658 code on my Ford?
Start by inspecting the wiring and connectors for damage, test the voltage at the affected circuit, and use a scan tool to monitor actuator performance.
5. Can I drive my Ford with the P0658 code active?
Driving with this code active is not recommended, as it can cause poor performance and potentially lead to further damage.
6. How do I fix the P0658 code on a Ford?
Repairs may involve replacing damaged wiring, repairing or replacing the faulty actuator, or reprogramming or replacing the PCM if needed.
7. What tools are needed to troubleshoot the P0658 code on a Ford?
You’ll need a scan tool, a multimeter for voltage testing, and possibly wiring diagrams for your specific Ford model.
8. How much does it cost to repair the P0658 code on a Ford?
Repair costs vary depending on the root cause, but wiring repairs may cost $100-$300, while actuator or PCM replacement can range from $300 to over $1,000.
9. Can failing sensors trigger the P0658 code in a Ford?
Yes, a failing sensor or actuator that relies on the Actuator Supply Voltage ‘A’ circuit can trigger this code.
10. Does the P0658 code require PCM replacement in all cases?
No, PCM replacement is only necessary if the PCM itself is found to be faulty after ruling out wiring and actuator issues.
