Code P0137 2016 Chevrolet Silverado Description
The diagnostic trouble code P0137 in a 2016 Chevrolet Silverado specifically refers to an issue with the Heated Oxygen Sensor (HO2S) Circuit having low voltage on Bank 1, Sensor 2. This sensor is responsible for monitoring the oxygen content in the exhaust gases after they have passed through the catalytic converter. The information provided by this sensor is crucial for the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion efficiency.
Common Causes of P0137 2016 Chevrolet Silverado
- Faulty Oxygen Sensor: The most common cause of the P0137 code is a malfunctioning Bank 1, Sensor 2 oxygen sensor.
- Wiring Issues: Damaged or corroded wiring connecting the oxygen sensor to the ECM can cause low voltage readings.
- Exhaust Leaks: Leaks in the exhaust system can affect the readings of the oxygen sensor, triggering the P0137 code.
- Engine Mechanical Problems: Issues such as vacuum leaks, a faulty EGR valve, or a leaking intake manifold gasket can impact the sensor's performance.
- ECM Malfunction: In rare cases, a malfunctioning ECM can also be the cause of the P0137 code.
Symptoms of P0137 2016 Chevrolet Silverado
- Check Engine Light: The most common symptom associated with the P0137 code is the illumination of the check engine light on the vehicle's dashboard.
- Poor Fuel Efficiency: A malfunctioning HO2S sensor can lead to incorrect air-fuel mixture adjustments, resulting in decreased fuel efficiency.
- Rough Idling: The engine may experience rough idling or stalling due to incorrect fuel mixture.
- Decreased Engine Performance: The vehicle may exhibit sluggish acceleration or overall reduced engine performance.
- Increased Emissions: A faulty HO2S sensor can lead to increased emissions, which may cause the vehicle to fail emissions tests.
How to Fix P0137 2016 Chevrolet Silverado
- Diagnose the Issue: Use a diagnostic scanner to retrieve the trouble codes and data from the oxygen sensor to pinpoint the exact cause of the problem.
- Inspect Wiring: Check the wiring connecting the oxygen sensor to the ECM for any damage or corrosion. Repair or replace as necessary.
- Check for Exhaust Leaks: Inspect the exhaust system for any leaks that could be affecting the sensor readings. Repair leaks as needed.
- Replace Oxygen Sensor: If the sensor is found to be faulty, replace Bank 1, Sensor 2 oxygen sensor with a new, OEM-quality sensor.
- Clear Codes and Test: After the repair is completed, clear the trouble codes from the ECM and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0137 2016 Chevrolet Silverado
The cost of repairing the P0137 code in a 2016 Chevrolet Silverado can vary depending on the specific cause of the issue. On average, the cost of replacing the Bank 1, Sensor 2 oxygen sensor ranges from $100 to $300 for the part alone. Labor costs at auto repair shops can range from $80 to $150 per hour, and the total repair cost may amount to $200 to $500 including parts and labor. It is advisable to check with local auto repair shops for more accurate estimates based on your location and vehicle specifics.
