P0058 2015 GMC Sierra Code - HO2S Heater Control Circuit High Voltage Bank 2 Sensor 2
Quick Answer
The P0058 diagnostic trouble code (DTC) for a 2015 GMC Sierra indicates a problem with the HO2S (Heated Oxygen Sensor) Heater Control Circuit High Voltage for Bank 2 Sensor 2. Common causes include Faulty HO2S: The Bank 2 Sensor 2 HO2S itself may be malfunctioning, causing the high voltage in the heater control circuit, Wiring Issues: Damaged or corroded wiring connecting the sensor to the ECM can disrupt the heater control circuit, ECM Malfunction: A problem with the engine control module (ECM) can also trigger the P0058 code by sending incorrect signals to the sensor. 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 2015 GMC Sierra Description
The P0058 diagnostic trouble code (DTC) for a 2015 GMC Sierra indicates a problem with the HO2S (Heated Oxygen Sensor) Heater Control Circuit High Voltage for Bank 2 Sensor 2. This sensor is responsible for 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. The heater control circuit is crucial for the sensor's operation, as it ensures accurate readings even in cold conditions by heating up the sensor quickly.
Common Causes of P0058 2015 GMC Sierra
- Faulty HO2S: The Bank 2 Sensor 2 HO2S itself may be malfunctioning, causing the high voltage in the heater control circuit.
- Wiring Issues: Damaged or corroded wiring connecting the sensor to the ECM can disrupt the heater control circuit.
- ECM Malfunction: A problem with the engine control module (ECM) can also trigger the P0058 code by sending incorrect signals to the sensor.
- Blown Fuse: A blown fuse in the heater control circuit can prevent the sensor from receiving power, leading to high voltage readings.
- Exhaust Leak: An exhaust leak near the sensor can affect its readings and trigger the P0058 code.
Symptoms of P0058 2015 GMC Sierra
- Check Engine Light: The most common symptom associated with the P0058 code is the illumination of the check engine light on the dashboard.
- Decreased Fuel Efficiency: A faulty HO2S heater control circuit can cause the engine to run rich or lean, leading to decreased fuel efficiency.
- Rough Idle: The engine may experience rough idling or hesitation when the HO2S heater control circuit is not functioning properly.
- Failed Emissions Test: If the issue is not resolved, the vehicle may fail emissions tests due to increased emissions caused by improper air-fuel mixture.
- Engine Misfires: In severe cases, the engine may experience misfires or hesitation during acceleration.
How to Fix P0058 2015 GMC Sierra
- Diagnose the Issue: Use a scan tool to read the DTC and perform a thorough inspection of the HO2S heater control circuit to pinpoint the exact cause of the problem.
- Replace HO2S: If the sensor is faulty, replace Bank 2 Sensor 2 with a new, OEM-quality sensor to ensure accurate readings and proper operation.
- Check Wiring: Inspect the wiring harness for any damage or corrosion, and repair or replace any affected wires to restore proper connectivity.
- Test ECM: Test the engine control module (ECM) to ensure it is sending the correct signals to the sensor and replace if necessary.
- Clear Codes: After completing the repairs, clear the DTC using a scan tool and test drive the vehicle to verify that the issue has been resolved.
Cost to Fix P0058 2015 GMC Sierra
The cost of repairing the P0058 code on a 2015 GMC Sierra can vary depending on the specific cause of the issue and the labor rates in your area. On average, replacing the HO2S sensor can cost between $150 to $300, while addressing wiring issues or ECM malfunctions may increase the total repair cost. Including parts and labor, the total repair cost for this issue could range from $200 to $500. It's recommended to consult with a trusted mechanic or auto repair shop to get an accurate estimate based on your vehicle's specific needs and location. Keep in mind that diagnostic time and labor rates can vary, so it's advisable to inquire about these factors before proceeding with the repair.

Frequently Asked Questions about P0058 2015 GMC Sierra Code
What does the OBDII code P0058 mean for a 2015 GMC Sierra?
P0058 indicates a problem with the heater control circuit in the downstream oxygen sensor (Bank 2 Sensor 2), specifically high voltage has been detected.
What are the common symptoms of code P0058 in a 2015 GMC Sierra?
Symptoms may include an illuminated check engine light, reduced fuel efficiency, poor engine performance, or difficulty passing emissions tests.
What causes the P0058 code to appear on a 2015 GMC Sierra?
Common causes include a faulty oxygen sensor, damaged wiring or connectors in the heater circuit, a blown fuse, or a malfunctioning ECM (engine control module).
How can I identify Bank 2 Sensor 2 on my 2015 GMC Sierra?
Bank 2 refers to the side of the engine opposite cylinder 1, and Sensor 2 is the downstream oxygen sensor located after the catalytic converter.
Can I drive my 2015 GMC Sierra with a P0058 code?
While the vehicle may still be drivable, prolonged driving with this code can lead to reduced fuel efficiency and possible damage to the catalytic converter.
How do I troubleshoot the P0058 code on my 2015 GMC Sierra?
Start by checking the wiring and connectors around Bank 2 Sensor 2 for damage or corrosion, inspect the fuse for the oxygen sensor heater circuit, and test the sensor itself for proper operation.
Does the P0058 code mean I need to replace the oxygen sensor?
Not necessarily. While a faulty oxygen sensor is a common cause, you should first inspect the wiring, connectors, and fuses before replacing the sensor.
