P0058 GMC Code - HO2S Heater Control Circuit High Voltage Bank 2 Sensor 2

Quick Answer

The P0058 GMC code refers to a problem with the HO2S (Heated Oxygen Sensor) Heater Control Circuit on Bank 2 Sensor 2. Common causes include Faulty HO2S Heater: The most common cause of the P0058 code is a malfunctioning HO2S heater in Bank 2 Sensor 2, Wiring Issues: Damaged or corroded wiring in the heater circuit can prevent the sensor from receiving the necessary voltage, ECM Malfunction: A problem with the engine control module (ECM) can also trigger this code by failing to properly regulate the heater circuit. 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 GMC Description

The P0058 GMC code refers to a problem with the HO2S (Heated Oxygen Sensor) Heater Control Circuit on Bank 2 Sensor 2. This sensor is responsible for monitoring the oxygen levels in the exhaust gases and sending this information to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. The heater control circuit is designed to heat up the sensor quickly to operating temperature for accurate readings.

Common Causes of P0058 GMC

  1. Faulty HO2S Heater: The most common cause of the P0058 code is a malfunctioning HO2S heater in Bank 2 Sensor 2.
  2. Wiring Issues: Damaged or corroded wiring in the heater circuit can prevent the sensor from receiving the necessary voltage.
  3. ECM Malfunction: A problem with the engine control module (ECM) can also trigger this code by failing to properly regulate the heater circuit.
  4. Exhaust Leak: A leak in the exhaust system near the sensor can cause the heater circuit to malfunction.
  5. Sensor Contamination: Contaminants such as oil or coolant can interfere with the sensor's operation and trigger the code.

Symptoms of P0058 GMC

  1. Check Engine Light: The most common symptom associated with the P0058 code is the illumination of the check engine light on the vehicle's dashboard.
  2. Poor Fuel Economy: A faulty HO2S heater control circuit can lead to incorrect air-fuel mixture adjustments, resulting in decreased fuel efficiency.
  3. Rough Idling: The engine may experience rough idling or hesitation when the HO2S sensor is not functioning properly.
  4. Failed Emissions Test: If the issue is not addressed, it can lead to increased emissions, causing the vehicle to fail an emissions test.
  5. Reduced Engine Performance: The engine may lack power or responsiveness due to incorrect sensor readings affecting the fuel delivery.

How to Fix P0058 GMC

  1. Diagnose the Issue: Use a scan tool to read the code and determine the specific cause of the problem.
  2. Inspect Wiring and Connections: Check the wiring harness and connections for any damage or corrosion, repairing or replacing as needed.
  3. Test HO2S Heater: Test the heater circuit of Bank 2 Sensor 2 to verify if the sensor itself is faulty.
  4. Replace HO2S Sensor: If the sensor is determined to be the issue, replace Bank 2 Sensor 2 with a new one.
  5. Clear Codes and Test Drive: Clear the codes from the ECM, and test drive the vehicle to ensure the issue has been resolved.

Cost to Fix P0058 GMC

The typical repair costs for addressing the P0058 code can vary depending on the specific cause of the issue. In general, replacing the HO2S sensor or repairing wiring/connectors can range from $150 to $400, including parts and labor. Additional costs may apply if the ECM needs to be replaced or if there are other underlying issues contributing to the code. It's recommended to consult with a qualified mechanic or auto repair shop for a more accurate estimate based on the vehicle's make and model, as well as local labor rates. Keep in mind that diagnosis time and labor rates can vary, so it's advisable to inquire about these factors before proceeding with the repair.

Tech Notes for P0058 GMC

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.
