P0058 2017 GMC Sierra Code - HO2S Heater Control Circuit High Voltage Bank 2 Sensor 2
Quick Answer
Heated Oxygen Sensors (HO2S) are used for fuel control and post catalyst monitoring. Common causes include Faulty Heated Oxygen Sensor (H2OS) Bank 2 Sensor 2, Heated Oxygen Sensor Bank 2 Sensor 2 harness is open shorted, Heated Oxygen Sensor Bank 2 Sensor 2 circuit poor electrical connection. 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.

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.
