P0058 Chevrolet 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.

Code P0058 Chevrolet Description

Heated Oxygen Sensors (HO2S) are used for fuel control and post catalyst monitoring. Each HO2S compares the oxygen content of the surrounding air with the oxygen content in the exhaust stream. The HO2S must reach an operating temperature to provide an accurate voltage signal. A heating element inside the HO2S minimizes the time required for the sensors to reach operating temperature. Voltage is provided to the heater by an ignition voltage circuit through a fuse. With the engine running, the ground is provided to the heater by the HO2S heater low control circuit through a low side driver within the Engine Control Module (ECM). The ECM uses Pulse Width Modulation (PWM) to control the HO2S heater operation to maintain a specific HO2S operating temperature range.
The Diagnostic Trouble Code (DTC) will be set when the ECM detects a short to voltage in the heater output low side driver circuit of the heated oxygen sensor when the heater is commanded ON for greater than 5 s.

Code Tech Notes

The code means that there is a problem with the heater element circuit of the heated oxygen sensor. The control module monitors how long it takes the sensor to warm up and start sending an adequate signal. The code is set when the sensor is taking too long to warm up. Water getting inside the heated oxygen sensor connector can cause the heated oxygen sensor fuse to blow. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors. If the fuse and connector are OK, replacing the O2 Sensor usually takes care of the problem.

What is the Cost to Diagnose the Code?

Labor: 1.0

To diagnose the P0058 Chevrolet code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P0058 Chevrolet Code

1. What does the OBDII code P0058 mean for a Chevrolet?

P0058 indicates a high voltage issue in the HO2S (Heated Oxygen Sensor) heater control circuit for Bank 2 Sensor 2.

2. What are the symptoms of P0058 in a Chevrolet?

Symptoms may include an illuminated check engine light, decreased fuel efficiency, rough idling, or failed emissions tests.

3. What causes the P0058 code to appear?

Common causes include a faulty oxygen sensor, damaged wiring, a short or open circuit, or a malfunctioning powertrain control module (PCM).

4. Which sensor is affected by the P0058 code?

The code refers to the downstream oxygen sensor (Sensor 2) on Bank 2, which monitors the catalytic converter's efficiency.

5. Can I drive my Chevrolet with a P0058 code?

While the vehicle may still be drivable, ignoring the code could lead to poor fuel economy and potential damage to the catalytic converter.

6. How do I diagnose the P0058 code in a Chevrolet?

Check the wiring and connectors for damage, test the oxygen sensor heater circuit for continuity, and verify the voltage levels with a multimeter.

7. How is the P0058 code repaired?

Repairs may involve replacing the oxygen sensor, repairing damaged wiring, or addressing PCM-related issues if necessary.

8. How much does it cost to fix a P0058 code on a Chevrolet?

The cost varies but typically ranges from $150 to $400, depending on whether only the sensor needs replacement or additional repairs are required.

9. Can a bad fuse cause the P0058 code?

Yes, a blown fuse related to the oxygen sensor heater circuit could trigger this code.

10. Is it necessary to clear the P0058 code after repairs?

Yes, after completing repairs, clear the code with an OBDII scanner and test drive to ensure it doesn’t reappear.
