Code P0058 Description

The P0058 diagnostic trouble code (DTC) refers to an issue with the HO2S (Heated Oxygen Sensor) Heater Control Circuit for Bank 2 Sensor 2. This specific sensor is located in the exhaust system after the catalytic converter on the side of the engine that contains the second cylinder bank. The purpose of the HO2S sensor is to measure the oxygen content in the exhaust gases to help the engine control module (ECM) adjust the air-fuel mixture for optimal performance and emissions.

Common Causes of P0058

  1. Faulty HO2S sensor
  2. Wiring or connector issues in the heater circuit
  3. Corrosion or damage to sensor connections
  4. ECM software or hardware issues
  5. Engine overheating causing damage to the sensor

Symptoms of P0058

  1. Check engine light illuminated on the dashboard
  2. Decreased fuel efficiency
  3. Rough idle or engine misfires
  4. Poor engine performance
  5. Increased emissions

How to Fix P0058

  1. Begin by diagnosing the issue using a scan tool to confirm the P0058 code and pinpoint the exact cause.
  2. Inspect the wiring and connectors associated with the HO2S sensor for any damage, corrosion, or loose connections. Repair or replace as needed.
  3. Test the HO2S sensor's heater circuit resistance to determine if it is within specifications. Replace the sensor if the resistance is too high.
  4. Clear the DTC and reset the ECM to see if the code returns. Test drive the vehicle to ensure the issue has been resolved.
  5. If the problem persists, further diagnostics may be needed to identify underlying issues such as ECM faults or engine overheating.

Cost to Fix P0058

The cost of repairing a P0058 code can vary depending on the cause of the issue. Typically, replacing a faulty HO2S sensor can cost between $100 to $200, while addressing wiring or connector problems may range from $50 to $150. Labor costs can add an additional $80 to $150 per hour, with the total repair bill potentially ranging from $150 to $500 or more. As mentioned earlier, actual costs can vary based on factors such as location, vehicle make and model, and the specific diagnosis and repair process required. It is recommended to obtain quotes from local auto repair shops for a more accurate estimate.

Tech Notes for P0058

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.

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.
