P0058 Infiniti Code - HO2S22 Heater Control Circuit High
Quick Answer
The P0058 code for Infiniti vehicles specifically refers to a problem with the Heater Control Circuit of the HO2S22 (Heated Oxygen Sensor 2 Bank 2). Common causes include Faulty Oxygen Sensor: A malfunctioning HO2S22 oxygen sensor could be the root cause of the Heater Control Circuit high voltage issue, Wiring Issues: Damaged or corroded wiring connected to the oxygen sensor can disrupt the Heater Control Circuit, Faulty ECM: A problem with the Engine Control Module (ECM) could also lead to the P0058 code being triggered. 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 Infiniti Description
The P0058 code for Infiniti vehicles specifically refers to a problem with the Heater Control Circuit of the HO2S22 (Heated Oxygen Sensor 2 Bank 2). The HO2S22 is a crucial component of the vehicle's emissions system, responsible for monitoring the oxygen levels in the exhaust gases to ensure proper fuel mixture and optimal engine performance. The Heater Control Circuit is designed to heat up the oxygen sensor quickly to achieve operating temperature for accurate readings. When this circuit is detected to be operating at a higher than normal voltage, the P0058 code is triggered.
Common Causes of P0058 Infiniti
- Faulty Oxygen Sensor: A malfunctioning HO2S22 oxygen sensor could be the root cause of the Heater Control Circuit high voltage issue.
- Wiring Issues: Damaged or corroded wiring connected to the oxygen sensor can disrupt the Heater Control Circuit.
- Faulty ECM: A problem with the Engine Control Module (ECM) could also lead to the P0058 code being triggered.
- Exhaust System Leaks: Leaks in the exhaust system can affect the readings of the oxygen sensor, causing the Heater Control Circuit to operate at a higher voltage.
- Electrical Short: An electrical short in the circuitry connected to the oxygen sensor can also cause the Heater Control Circuit high voltage fault.
Symptoms of P0058 Infiniti
- 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 HO2S22 Heater Control Circuit can lead to decreased fuel efficiency as the engine may not be running at optimal levels.
- Rough Idling: The engine may experience rough idling or hesitation when the oxygen sensor is not functioning correctly.
- Failed Emissions Test: If the oxygen sensor is not providing accurate readings, the vehicle may fail an emissions test due to increased emissions output.
How to Fix P0058 Infiniti
- Diagnose the Issue: Use an OBD-II scanner to read and record the P0058 code, then inspect the oxygen sensor and its wiring for any visible damage.
- Test the Oxygen Sensor: Perform a test on the HO2S22 oxygen sensor to determine if it is functioning properly or needs to be replaced.
- Check Wiring and Connections: Inspect the wiring harness and connections to the oxygen sensor for any signs of damage, corrosion, or loose connections.
- Replace Oxygen Sensor: If the oxygen sensor is faulty, replace it with a new sensor compatible with your Infiniti vehicle.
- Clear Code: After repairing or replacing the components, clear the P0058 code from the vehicle's ECM using the OBD-II scanner to reset the Check Engine Light.
Cost to Fix P0058 Infiniti
The typical repair costs for addressing a P0058 code on an Infiniti vehicle can vary depending on the specific cause of the issue and the cost of parts and labor. On average, the cost of replacing an oxygen sensor can range from $200 to $400, including parts and labor. However, additional costs may be incurred if wiring repairs or ECM diagnostics are required. It is recommended to consult with a certified mechanic or auto repair shop for a more accurate estimate based on your vehicle's make and model. Keep in mind that labor rates can vary between different locations and service providers.
