Code P0058 2014 Chevrolet Silverado Description

Heated Oxygen Sensors (HO2S) are used for fuel control and post catalyst monitoring. Each HO2S compares the oxygen content of the surrounding air with the oxygen content in the exhaust stream. The HO2S must reach an operating temperature to provide an accurate voltage signal. A heating element inside the HO2S minimizes the time required for the sensors to reach operating temperature. Voltage is provided to the heater by an ignition voltage circuit through a fuse. With the engine running, the ground is provided to the heater by the HO2S heater low control circuit through a low side driver within the Engine Control Module (ECM). The ECM uses Pulse Width Modulation (PWM) to control the HO2S heater operation to maintain a specific HO2S operating temperature range.
The Diagnostic Trouble Code (DTC) will be set when the ECM detects a short to voltage in the heater output low side driver circuit of the heated oxygen sensor when the heater is commanded ON for greater than 5 s.

Code Tech Notes

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.

What is the Cost to Diagnose the Code?

Labor: 1.0

To diagnose the P0058 2014 Chevrolet Silverado code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P0058 2014 Chevrolet Silverado Code

What does the OBDII code P0058 mean for my 2014 Chevrolet Silverado?

P0058 indicates a problem with the heater control circuit for the oxygen sensor located in Bank 2, Sensor 2. It typically means there is high voltage present in the circuit.

What are the common symptoms of the P0058 code?

Common symptoms may include poor fuel economy, increased emissions, rough idle, and the check engine light being illuminated on the dashboard.

What could cause the P0058 code to trigger?

Possible causes include a faulty oxygen sensor, damaged wiring or connectors, a blown fuse, or issues with the engine control module (ECM).

How can I diagnose the P0058 code?

To diagnose the code, inspect the wiring and connectors for damage, check the sensor for proper operation, and test the heater circuit voltage and resistance.

Can I drive my 2014 Chevrolet Silverado with the P0058 code?

While you can drive the vehicle, it's not advisable, as it may lead to decreased performance, increased emissions, and potential damage to other components.

What is the typical cost for repairing a P0058 code?

Repair costs can vary widely, but replacing the oxygen sensor generally ranges from $100 to $300, depending on labor rates and parts pricing.

Should I replace the oxygen sensor immediately after getting a P0058 code?

Not necessarily. First, conduct a thorough diagnostic to confirm the sensor is faulty and to rule out other issues such as wiring problems.

What type of oxygen sensor is involved with the P0058 code?

The code refers to the downstream oxygen sensor (Sensor 2) located after the catalytic converter on Bank 2 of the engine.

How can I prevent the P0058 code from returning after repairs?

To prevent recurrence, ensure all connections are secure, check for any exhaust leaks, and keep the engine well-maintained with regular servicing.

Is it safe to ignore the P0058 code?

Ignoring the P0058 code is not safe, as it can lead to more serious engine issues, reduced fuel efficiency, and increased emissions. It's best to address it promptly.
