Code P0058 2017 GMC Sierra Description
The P0058 diagnostic trouble code (DTC) for a 2017 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 voltage in the heater control circuit for the downstream oxygen sensor located on the second bank of cylinders is higher than normal. The oxygen sensor is a crucial component of the vehicle's emissions control system, as it measures the amount of oxygen in the exhaust gases to help the engine control module (ECM) adjust the air-fuel mixture for optimal combustion.
Common Causes of P0058 2017 GMC Sierra
- Faulty oxygen sensor heater.
- Wiring or connector issues in the heater control circuit.
- ECM software malfunction.
- Exhaust leaks near the oxygen sensor.
- Engine coolant leaking onto the sensor.
Symptoms of P0058 2017 GMC Sierra
- Check engine light illuminated on the dashboard.
- Decreased fuel efficiency.
- Rough idling or engine misfires.
- Failed emissions test.
- Reduced engine performance.
How to Fix P0058 2017 GMC Sierra
- Begin by using a scan tool to verify the P0058 code and identify the specific sensor causing the issue.
- Inspect the wiring and connectors in the heater control circuit for any damage or corrosion. Repair or replace as needed.
- Test the oxygen sensor heater for proper resistance and functionality. Replace the sensor if it fails the test.
- Clear the DTC and reset the ECM to see if the code returns. Monitor the sensor readings to ensure proper operation.
- If the issue persists, further diagnostics may be required to check for underlying engine or exhaust system problems.
Cost to Fix P0058 2017 GMC Sierra
The typical repair costs for addressing a P0058 code on a 2017 GMC Sierra can range from $150 to $400, including parts and labor. However, actual costs may vary depending on the specific diagnosis time and labor rates at auto repair shops, which can range from $80 to $150 per hour. It's recommended to consult with a professional mechanic to get an accurate estimate based on your location and vehicle details.

Frequently Asked Questions about P0058 2017 GMC Sierra Code
1. What does the OBDII code P0058 mean on a 2017 GMC Sierra?
P0058 indicates a high voltage issue in the heater control circuit for the oxygen sensor (HO2S) on Bank 2 Sensor 2.
2. What are the symptoms of code P0058 in a 2017 GMC Sierra?
Symptoms may include an illuminated check engine light, reduced fuel efficiency, failed emissions tests, or no noticeable symptoms at all.
3. What causes the P0058 code to appear on a 2017 GMC Sierra?
Common causes include a faulty oxygen sensor, damaged wiring or connectors in the heater circuit, or a malfunctioning PCM (Powertrain Control Module).
4. Which oxygen sensor is Bank 2 Sensor 2 in the 2017 GMC Sierra?
Bank 2 Sensor 2 is the downstream oxygen sensor located after the catalytic converter on the side of the engine opposite Cylinder 1.
5. Can I drive my 2017 GMC Sierra with the P0058 code?
While it might be safe to drive for a short period, ignoring the issue can lead to reduced fuel efficiency and potential damage to the catalytic converter over time.
6. How do I fix the P0058 code on a 2017 GMC Sierra?
Repairs may involve replacing the Bank 2 Sensor 2 oxygen sensor, repairing damaged wiring or connectors, or addressing a faulty PCM if needed.
7. How do I diagnose the P0058 code on my 2017 GMC Sierra?
Start by visually inspecting the wiring and connectors for damage, use a multimeter to check the heater circuit voltage, and test the oxygen sensor for proper resistance.
8. How much does it cost to fix the P0058 code on a 2017 GMC Sierra?
Replacing the oxygen sensor typically costs $100-$300, including parts and labor. Wiring repairs or PCM replacement could increase costs.
9. Can a bad oxygen sensor cause other problems besides the P0058 code?
Yes, a faulty oxygen sensor can lead to poor fuel economy, increased emissions, and potential damage to the catalytic converter if not addressed.
10. Will clearing the P0058 code solve the problem on my 2017 GMC Sierra?
Clearing the code may temporarily turn off the check engine light, but the underlying issue must be fixed to prevent the code from returning.
