Code P0059 2016 GMC Sierra Description
The P0059 diagnostic trouble code (DTC) for a 2016 GMC Sierra relates to the heated oxygen sensor (HO2S) heater circuit in Bank 2 Sensor 1. This code indicates that there is a problem with the electrical resistance in the heater circuit of the oxygen sensor located in the exhaust system. The oxygen sensor plays a crucial role in monitoring the oxygen levels in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion.
Common Causes of P0059 2016 GMC Sierra
- Faulty Oxygen Sensor: The most common cause of this code is a malfunctioning oxygen sensor with a defective heater circuit.
- Wiring Issues: Damage to the wiring harness or connectors connected to the oxygen sensor can disrupt the heater circuit.
- Blown Fuse: A blown fuse in the oxygen sensor heater circuit can prevent the sensor from receiving power.
- ECM Malfunction: A malfunction in the engine control module (ECM) can also trigger this code if it fails to properly control the oxygen sensor heater circuit.
Symptoms of P0059 2016 GMC Sierra
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Decreased Fuel Efficiency: A faulty oxygen sensor heater circuit can cause the engine to run less efficiently, resulting in decreased fuel economy.
- Rough Idling: The engine may experience rough idling or hesitation when the oxygen sensor is not functioning properly.
- Failed Emissions Test: If the oxygen sensor is not providing accurate readings, the vehicle may fail an emissions test due to increased emissions.
- Engine Misfires: In severe cases, a malfunctioning oxygen sensor can lead to engine misfires and poor overall performance.
How to Fix P0059 2016 GMC Sierra
- Diagnose the Issue: Use a scan tool to retrieve the specific trouble code and perform a thorough inspection of the oxygen sensor and its related components.
- Replace Oxygen Sensor: If the oxygen sensor is determined to be faulty, replace Bank 2 Sensor 1 with a new, OEM-quality sensor.
- Check Wiring: Inspect the wiring harness and connectors for any signs of damage or corrosion, and repair or replace as needed.
- Test Heater Circuit: Verify that the heater circuit is receiving power and functioning correctly after the replacement of the oxygen sensor.
- Clear Codes: Clear the DTC from the ECM memory using a scan tool and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0059 2016 GMC Sierra
The typical repair costs for addressing a P0059 code on a 2016 GMC Sierra can range from $200 to $500, including parts and labor. However, it's important to note that actual repair costs may vary depending on the specific diagnosis time and labor rates at auto repair shops. Rates can fluctuate based on factors such as location, vehicle make and model, and engine type. It's recommended to obtain quotes from local auto repair shops for a more accurate estimate.
