P0058 Code - HO2S Heater Control Circuit High 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 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.

Frequently Asked Questions about P0058 Code

What does the OBDII code P0058 mean?

P0058 indicates a high voltage issue in the heater control circuit for the oxygen sensor located at Bank 2, Sensor 2.

What are the common symptoms of P0058?

Symptoms can include an illuminated check engine light, decreased fuel efficiency, rough idling, or failure to pass emissions tests.

What causes the P0058 code?

Common causes include a short circuit in the wiring, a faulty oxygen sensor, a damaged heater control circuit, or issues with the vehicle’s PCM.

How can I diagnose P0058?

Inspect the wiring and connectors for damage, test the oxygen sensor’s heater circuit for continuity, and check for voltage irregularities using a multimeter.

Can a faulty oxygen sensor trigger the P0058 code?

Yes, a malfunctioning oxygen sensor heater element can cause the P0058 code to appear.

How does P0058 affect vehicle performance?

This code can lead to inefficient fuel combustion, reduced fuel economy, and higher emissions output.

Can I drive with the P0058 code?

Driving with this code is possible but not recommended, as it can worsen fuel efficiency and damage the catalytic converter over time.

How do I fix the P0058 code?

Repairs may involve replacing the oxygen sensor, repairing damaged wiring, or addressing issues with the PCM.

How much does it cost to repair P0058?

Repair costs vary depending on the issue but typically range from $200 to $400 for parts and labor.

Is P0058 a serious issue?

While not immediately critical, ignoring P0058 can lead to long-term damage to the catalytic converter and higher emissions levels.
