P0058 Suzuki Code - HO2S22 Heater Control Circuit High

Quick Answer

The P0058 Suzuki diagnostic trouble code (DTC) refers to an issue with the Heater Control Circuit of the HO2S22 sensor. Common causes include Faulty HO2S22 Sensor: A malfunctioning downstream oxygen sensor can trigger the P0058 code, Wiring Issues: Damaged or corroded wiring in the heater control circuit can disrupt the sensor's operation, Heater Circuit Malfunction: Issues with the heater circuit, such as a blown fuse or faulty relay, can prevent the sensor from reaching the required temperature. 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 Suzuki Description

The P0058 Suzuki diagnostic trouble code (DTC) refers to an issue with the Heater Control Circuit of the HO2S22 sensor. The HO2S22 sensor, also known as the downstream oxygen sensor, plays a crucial role in monitoring the oxygen levels in the exhaust gases. The heater control circuit is responsible for ensuring that the sensor reaches and maintains the optimal operating temperature for accurate readings.

Common Causes of P0058 Suzuki

  1. Faulty HO2S22 Sensor: A malfunctioning downstream oxygen sensor can trigger the P0058 code.
  2. Wiring Issues: Damaged or corroded wiring in the heater control circuit can disrupt the sensor's operation.
  3. Heater Circuit Malfunction: Issues with the heater circuit, such as a blown fuse or faulty relay, can prevent the sensor from reaching the required temperature.
  4. ECM Malfunction: A malfunctioning Engine Control Module (ECM) can also cause the P0058 code to be triggered.

Symptoms of P0058 Suzuki

  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. Decreased Fuel Efficiency: A malfunctioning HO2S22 Heater Control Circuit can lead to poor fuel combustion, resulting in decreased fuel efficiency.
  3. Rough Idle: The engine may experience rough idling or hesitation when the HO2S22 sensor is not functioning correctly.
  4. Failed Emissions Test: If the P0058 code is not addressed, it can lead to increased emissions, causing the vehicle to fail emissions tests.

How to Fix P0058 Suzuki

  1. Diagnose the Issue: Use a diagnostic scanner to retrieve the DTC and pinpoint the exact cause of the P0058 code.
  2. Inspect Wiring and Connections: Check the wiring and connections related to the HO2S22 sensor for any damage or corrosion. Repair or replace as needed.
  3. Test Heater Circuit: Verify the functionality of the heater circuit by checking the fuse, relay, and wiring for continuity. Replace any faulty components.
  4. Replace HO2S22 Sensor: If the sensor is determined to be faulty, replace it with a new, OEM-equivalent sensor.
  5. Clear DTC and Test Drive: Clear the DTC from the ECM memory, and test drive the vehicle to ensure that the issue has been resolved.

Cost to Fix P0058 Suzuki

The typical repair costs for addressing the P0058 Suzuki code can range from $150 to $400, including parts and labor. However, it's essential to note that the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. Most auto repair shops charge between $80 and $150 per hour for labor, but rates may be higher in metropolitan areas or at dealerships, while independent shops may offer lower rates. It's recommended to inquire about local rates for a more accurate estimate.

When is the Code Detected?

The P0058 is set when the ECM detects an excessively high voltage through the heated oxygen sensor heater circuit
