Code P0658 Mercury Description
The P0658 diagnostic trouble code (DTC) for Mercury vehicles indicates an issue with the actuator supply voltage 'A' circuit being too low. This code is typically stored in the Engine Control Module (ECM) when the voltage supplied to a specific actuator or component falls below the predetermined threshold. In this case, the 'A' circuit refers to a specific electrical circuit that supplies power to a particular actuator or component in the vehicle's system.
Common Causes of P0658 Mercury
- Faulty wiring or connectors in the actuator supply voltage circuit
- Malfunctioning actuator or component
- Defective Engine Control Module (ECM)
- Drained or weak battery
- Corrosion or damage to electrical connections
Symptoms of P0658 Mercury
- Check engine light illuminated on the dashboard
- Rough idling or engine misfires
- Poor acceleration or lack of power
- Stalling or difficulty starting the vehicle
- Decreased fuel efficiency
How to Fix P0658 Mercury
- Perform a comprehensive diagnostic scan to retrieve the fault code and identify the specific actuator or component affected.
- Inspect the wiring, connectors, and electrical connections related to the actuator supply voltage 'A' circuit for any signs of damage or corrosion.
- Test the actuator or component for proper functionality and replace if necessary.
- Check the battery voltage and charging system to ensure they are operating within specifications.
- Clear the fault code, reset the ECM, and test drive the vehicle to verify that the issue has been resolved.
Cost to Fix P0658 Mercury
The typical repair costs for addressing the P0658 code on a Mercury vehicle can range from $100 to $300, depending on the specific cause of the issue and the required repairs. Parts such as wiring harnesses, actuators, or an ECM replacement may contribute to the overall cost. Additionally, labor rates at auto repair shops can vary, with hourly rates typically ranging between $80 and $150. It is advisable to contact local repair shops for a more accurate estimate based on your vehicle's make and model, as well as the extent of the necessary repairs.
