P0058 2016 GMC Sierra Code - HO2S Heater Control Circuit High Voltage Bank 2 Sensor 2
Quick Answer
The P0058 diagnostic trouble code (DTC) for a 2016 GMC Sierra refers to an issue with the HO2S (Heated Oxygen Sensor) Heater Control Circuit High Voltage for Bank 2 Sensor 2. Common causes include Faulty Oxygen Sensor: The most common cause of the P0058 code is a faulty oxygen sensor heater in Bank 2 Sensor 2, Wiring Harness Damage: Damage to the wiring harness that connects the oxygen sensor to the ECM can cause high voltage in the heater circuit, Blown Fuse: A blown fuse in the oxygen sensor heater circuit can prevent the sensor from receiving power and trigger the P0058 code. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P0058 2016 GMC Sierra Description
The P0058 diagnostic trouble code (DTC) for a 2016 GMC Sierra refers to an issue with the HO2S (Heated Oxygen Sensor) Heater Control Circuit High Voltage for Bank 2 Sensor 2. This code indicates that the oxygen sensor located downstream of the catalytic converter on the second bank of cylinders is experiencing a high voltage condition in its heater circuit. The heater circuit is responsible for quickly bringing the oxygen sensor up to operating temperature to accurately measure the oxygen content in the exhaust gases.
Common Causes of P0058 2016 GMC Sierra
- Faulty Oxygen Sensor: The most common cause of the P0058 code is a faulty oxygen sensor heater in Bank 2 Sensor 2.
- Wiring Harness Damage: Damage to the wiring harness that connects the oxygen sensor to the ECM can cause high voltage in the heater circuit.
- Blown Fuse: A blown fuse in the oxygen sensor heater circuit can prevent the sensor from receiving power and trigger the P0058 code.
- ECM Malfunction: In rare cases, a malfunction in the engine control module (ECM) can cause issues with the oxygen sensor heater circuit.
- Exhaust Leak: An exhaust leak near the oxygen sensor can cause incorrect readings and trigger the P0058 code.
Symptoms of P0058 2016 GMC Sierra
- Check Engine Light: The most common symptom associated with the P0058 code is the illumination of the check engine light on the vehicle's dashboard.
- Decreased Fuel Efficiency: A malfunctioning oxygen sensor can lead to decreased fuel efficiency as the ECM struggles to adjust the air-fuel mixture.
- Rough Idle: The engine may experience a rough idle or hesitation during acceleration due to inaccurate oxygen sensor readings.
- Failed Emissions Test: If the oxygen sensor is not functioning properly, the vehicle may fail emissions tests due to increased emissions levels.
- Engine Misfires: In severe cases, the high voltage condition in the oxygen sensor heater circuit can lead to engine misfires or stalling.
How to Fix P0058 2016 GMC Sierra
- Diagnose the Issue: Use a scan tool to read the DTC and pinpoint the specific oxygen sensor causing the high voltage condition.
- Inspect Wiring and Fuse: Check the wiring harness for damage or corrosion, and inspect the fuse related to the oxygen sensor heater circuit.
- Replace Oxygen Sensor: If the oxygen sensor heater is faulty, replace Bank 2 Sensor 2 with a new, OEM-quality sensor.
- Clear DTCs: After replacing the oxygen sensor, clear the DTCs using a scan tool to reset the check engine light.
- Test Drive: Take the vehicle for a test drive to ensure that the repair has resolved the issue and that the check engine light remains off.
Cost to Fix P0058 2016 GMC Sierra
The typical repair costs for addressing the P0058 code on a 2016 GMC Sierra can vary depending on the specific cause of the issue. In general, the cost of a new oxygen sensor for Bank 2 Sensor 2 can range from $100 to $200, depending on the brand and quality of the sensor. Labor costs for replacing the sensor and diagnosing the issue can range from $100 to $300, depending on the shop's hourly rates and the complexity of the repair.
