P0658 2018 Chevrolet Silverado Code - Actuator High Control Circuit Group 1 Low Voltage
Quick Answer
The P0658 diagnostic trouble code (DTC) for a 2018 Chevrolet Silverado refers to an issue with the Actuator High Control Circuit Group 1 Low Voltage. Common causes include Faulty Actuator: The actuator itself may be malfunctioning, leading to low voltage in the control circuit, Damaged Wiring or Connectors: Corrosion, fraying, or damage to the wiring or connectors in the control circuit can cause low voltage issues, Faulty Powertrain Control Module (PCM): A malfunctioning PCM can send incorrect signals to the actuator, resulting in low voltage in the control circuit. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0658 2018 Chevrolet Silverado Description
The P0658 diagnostic trouble code (DTC) for a 2018 Chevrolet Silverado refers to an issue with the Actuator High Control Circuit Group 1 Low Voltage. This code indicates that there is a problem with the electrical circuit that controls the actuator, which is responsible for regulating various components in the vehicle. In this case, the low voltage in the control circuit can lead to improper functioning of the actuator, potentially affecting the performance of the vehicle.
Common Causes of P0658 2018 Chevrolet Silverado
- Faulty Actuator: The actuator itself may be malfunctioning, leading to low voltage in the control circuit.
- Damaged Wiring or Connectors: Corrosion, fraying, or damage to the wiring or connectors in the control circuit can cause low voltage issues.
- Faulty Powertrain Control Module (PCM): A malfunctioning PCM can send incorrect signals to the actuator, resulting in low voltage in the control circuit.
- Electrical Short: An electrical short in the control circuit can disrupt the voltage supply to the actuator.
- Battery or Alternator Issues: Problems with the vehicle's battery or alternator can affect the voltage levels in the control circuit, triggering the P0658 code.
Symptoms of P0658 2018 Chevrolet Silverado
- Check Engine Light: The most common symptom associated with the P0658 code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Reduced Engine Performance: The vehicle may experience a decrease in engine power or responsiveness due to the actuator not functioning properly.
- Poor Fuel Efficiency: A malfunctioning actuator can lead to inefficient fuel combustion, resulting in reduced fuel efficiency.
- Rough Idle: The engine may idle roughly or inconsistently, indicating a problem with the actuator control circuit.
- Stalling: In severe cases, the vehicle may stall or have difficulty starting due to the actuator issue.
How to Fix P0658 2018 Chevrolet Silverado
- Diagnose the Issue: Use a diagnostic scanner to retrieve the specific DTC and pinpoint the cause of the low voltage in the actuator control circuit.
- Inspect Wiring and Connectors: Check the wiring and connectors in the control circuit for any damage or corrosion. Repair or replace as needed.
- Test Actuator Functionality: Test the actuator to ensure it is functioning correctly. Replace if necessary.
- Check Powertrain Control Module (PCM): Inspect the PCM for any signs of damage or malfunction. Replace if needed.
- Clear DTC and Test Drive: Clear the DTC from the vehicle's computer, and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0658 2018 Chevrolet Silverado
The typical repair costs for addressing a P0658 code on a 2018 Chevrolet Silverado can vary depending on the specific cause of the issue. In general, the cost of parts such as a new actuator, wiring, connectors, or PCM can range from $100 to $500 or more. Labor costs at auto repair shops typically range from $80 to $150 per hour, with the total repair bill potentially amounting to several hundred dollars.
