P0659 2016 GMC Sierra Code - Actuator High Control Circuit Group 1 High Voltage
Quick Answer
The P0659 diagnostic trouble code (DTC) for a 2016 GMC Sierra indicates an issue with the Actuator High Control Circuit Group 1 High Voltage. Common causes include Faulty Wiring: Damaged or corroded wiring in the actuator control circuit can lead to high voltage readings, Defective Actuator: A malfunctioning actuator can cause the control circuit to receive incorrect voltage signals, Sensor Malfunction: Issues with sensors that provide input to the actuator control circuit can trigger the P0659 code. 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 P0659 2016 GMC Sierra Description
The P0659 diagnostic trouble code (DTC) for a 2016 GMC Sierra indicates an issue with the Actuator High Control Circuit Group 1 High Voltage. This code specifically points to a problem with the electrical circuit that controls the actuator, which is responsible for adjusting various components in the vehicle such as the throttle, exhaust gas recirculation (EGR) valve, or other systems depending on the specific application.
Common Causes of P0659 2016 GMC Sierra
- Faulty Wiring: Damaged or corroded wiring in the actuator control circuit can lead to high voltage readings.
- Defective Actuator: A malfunctioning actuator can cause the control circuit to receive incorrect voltage signals.
- Sensor Malfunction: Issues with sensors that provide input to the actuator control circuit can trigger the P0659 code.
- Poor Electrical Ground: A weak or faulty ground connection can result in high voltage in the actuator control circuit.
- ECM/PCM Malfunction: A problem with the engine control module (ECM) or powertrain control module (PCM) can also cause the actuator high voltage issue.
Symptoms of P0659 2016 GMC Sierra
- Check Engine Light: The most common symptom associated with the P0659 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 improper actuator operation.
- Poor Fuel Efficiency: High voltage in the actuator control circuit can lead to inefficient fuel combustion, resulting in decreased fuel economy.
- Rough Idling: The engine may idle roughly or inconsistently, causing vibrations or shaking in the vehicle.
- Stalling: In severe cases, the vehicle may stall or have difficulty starting due to the actuator control circuit issue.
How to Fix P0659 2016 GMC Sierra
- Diagnose the Issue: Use a scan tool to retrieve the DTC and perform a thorough inspection of the actuator control circuit, wiring, connectors, and related components.
- Repair or Replace Wiring: Repair any damaged wiring or connectors in the actuator control circuit. Replace components as necessary.
- Test Sensors: Check the operation of sensors related to the actuator control circuit and replace any faulty sensors.
- Replace Actuator: If the actuator is found to be defective, replace it with a new unit to ensure proper operation.
- Clear Codes and Test Drive: Clear the DTC from the vehicle's ECM/PCM memory, then test drive the vehicle to verify that the issue has been resolved.
Cost to Fix P0659 2016 GMC Sierra
The typical repair costs for addressing a P0659 code on a 2016 GMC Sierra can range from $200 to $500, including parts and labor. However, the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. Most auto repair shops charge between $80 and $150 per hour for labor, but rates may be higher in metropolitan areas or at dealerships, while independent shops often charge less. It is recommended to obtain quotes from local repair shops for a more accurate estimate.
