P0058 2005 Infiniti G35 Code - HO2S22 Heater Control Circuit High

Quick Answer

The P0058 diagnostic trouble code (DTC) in a 2005 Infiniti G35 indicates an issue with the Heater Control Circuit of the HO2S22 (Heated Oxygen Sensor 2 Bank 2). Common causes include Faulty HO2S22: The sensor itself may be malfunctioning, causing the heater control circuit voltage to be too high, Wiring Issues: Damaged or corroded wiring connections to the HO2S22 can disrupt the heater circuit, ECM Malfunction: A problem with the engine control module can also trigger the P0058 code. 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 2005 Infiniti G35 Description

The P0058 diagnostic trouble code (DTC) in a 2005 Infiniti G35 indicates an issue with the Heater Control Circuit of the HO2S22 (Heated Oxygen Sensor 2 Bank 2). The HO2S22 is responsible for monitoring the oxygen levels in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. The heater control circuit is designed to quickly bring the sensor up to operating temperature for accurate readings.
