P0058 2004 Infiniti G35 Code - HO2S22 Heater Control Circuit High
Quick Answer
Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. Common causes include Faulty Heated Oxygen Sensor (H2OS) Bank 2 Sensor 2, Heated Oxygen Sensor (H2OS) Bank 2 Sensor 2 harness is open shorted, Heated Oxygen Sensor (H2OS) 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 2004 Infiniti G35 Description
In order to achieve the require temperature, a heater element is included inside the heated oxygen sensor. The ECM controls the heated oxygen sensor heater element based on signals from the engine coolant temperature and engine load. The ECM controls the heater element circuit by allowing current flow to ground.
The ECM monitors the voltage signal received through the heater element circuit and determines the state of the circuit by comparing the voltage detected with the factory specifications.
What are the Possible Causes of the DTC P0058 2004 Infiniti G35?
- Faulty Heated Oxygen Sensor (H2OS) Bank 2 Sensor 2
- Heated Oxygen Sensor (H2OS) Bank 2 Sensor 2 harness is open shorted
- Heated Oxygen Sensor (H2OS) Bank 2 Sensor 2 circuit poor electrical connection
- Heated Oxygen Sensor (H2OS) Bank 2 Sensor 2 circuit fuse
- Faulty Engine Control Module (ECM)
How to Fix the DTC P0058 2004 Infiniti G35?

Frequently Asked Questions about P0058 2004 Infiniti G35 Code
1. What does the OBDII code P0058 mean on a 2004 Infiniti G35?
P0058 indicates an issue with the heater control circuit for the oxygen sensor (HO2S) located on Bank 2, Sensor 2. Specifically, the circuit voltage is higher than expected.
2. What are the symptoms of code P0058 in a 2004 Infiniti G35?
Common symptoms include an illuminated check engine light, reduced fuel efficiency, failed emissions tests, and possible rough idling.
3. What causes code P0058 in a 2004 Infiniti G35?
Possible causes include a faulty oxygen sensor, damaged wiring or connectors in the heater control circuit, a blown fuse, or a malfunctioning powertrain control module (PCM).
4. Can I drive my 2004 Infiniti G35 with a P0058 code?
While the car may be drivable, it's not recommended to ignore the code, as it can lead to poor fuel economy, increased emissions, and potential damage to the catalytic converter over time.
5. How do I diagnose code P0058 on a 2004 Infiniti G35?
Start by inspecting the oxygen sensor wiring and connectors for damage. Use a multimeter to test the heater circuit for continuity and confirm proper voltage at the connector. If no issues are found, test or replace the oxygen sensor.
6. How do I fix the P0058 code on a 2004 Infiniti G35?
Repairs may include replacing the Bank 2, Sensor 2 oxygen sensor, repairing damaged wiring or connectors, replacing a blown fuse, or addressing PCM-related issues if all else checks out.
7. Where is Bank 2, Sensor 2 located on a 2004 Infiniti G35?
Bank 2 refers to the side of the engine opposite the number one cylinder, and Sensor 2 is the downstream oxygen sensor located after the catalytic converter.
8. What tools are needed to fix a P0058 code on a 2004 Infiniti G35?
Common tools include a diagnostic scanner, multimeter, oxygen sensor socket, and basic hand tools for removing and replacing components.
9. How much does it cost to repair a P0058 code on a 2004 Infiniti G35?
The cost depends on the issue. Replacing an oxygen sensor typically costs $150-$300, while repairing wiring can vary widely based on the damage.
10. Can a P0058 code cause long-term damage to my 2004 Infiniti G35?
If left unresolved, the code can lead to excessive fuel consumption, increased emissions, and potential damage to the catalytic converter, which can be expensive to replace.
