Code P0137 2016 Honda CR-V Description
The P0137 diagnostic trouble code (DTC) on a 2016 Honda CR-V specifically refers to the Secondary Heated Oxygen Sensor 2 Circuit Low Voltage. This code indicates that the oxygen sensor located after the catalytic converter in the exhaust system is not sending the expected voltage signal to the engine control module (ECM). The oxygen sensor plays a crucial role in monitoring the air-fuel ratio of the engine to ensure optimal combustion and reduce emissions. When the sensor detects a low voltage signal, it suggests that the sensor is not functioning correctly, which can lead to various performance issues in the vehicle.
Common Causes of P0137 2016 Honda CR-V
- Faulty Oxygen Sensor: The most common cause of the P0137 code is a malfunctioning secondary heated oxygen sensor 2.
- Wiring Issues: Damaged or corroded wiring connecting the oxygen sensor to the ECM can disrupt the voltage signal.
- Exhaust System Leaks: Exhaust leaks near the oxygen sensor can lead to false readings and trigger the code.
- Exhaust System Contamination: Contaminants such as oil or coolant entering the exhaust system can affect the sensor's performance.
- ECM Malfunction: In rare cases, a faulty engine control module can cause erroneous readings from the oxygen sensor.
Symptoms of P0137 2016 Honda CR-V
- 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 Economy: A faulty oxygen sensor can lead to inaccurate fuel mixture adjustments, resulting in decreased fuel efficiency.
- Rough Idling: The engine may experience rough idling or misfires due to incorrect air-fuel ratio settings.
- Reduced Engine Performance: The vehicle may exhibit a loss of power or responsiveness when accelerating.
- Emission Test Failure: If the oxygen sensor is not functioning correctly, the vehicle may fail emissions tests due to increased emissions.
How to Fix P0137 2016 Honda CR-V
- Diagnose the Issue: Use an OBD-II scanner to retrieve the specific trouble code and determine if the oxygen sensor is the root cause of the problem.
- Inspect Wiring and Connections: Check the wiring harness and connectors for any damage or corrosion, repairing or replacing as necessary.
- Replace Oxygen Sensor: If the sensor is confirmed to be faulty, replace the secondary heated oxygen sensor 2 with a new, OEM-quality part.
- Clear Error Codes: After replacing the sensor, clear the error codes stored in the ECM's memory to reset the check engine light.
- Test Drive and Recheck: Take the vehicle for a test drive to ensure that the issue has been resolved, and recheck for any remaining error codes.
Cost to Fix P0137 2016 Honda CR-V
The typical repair costs for addressing the P0137 code on a 2016 Honda CR-V can vary depending on the specific cause of the issue and the labor rates at the auto repair shop. In general, the cost of replacing the secondary heated oxygen sensor 2 can range from $150 to $300 for the part alone. Including labor costs, the total repair bill may amount to $250 to $500 or more. It's essential to consider additional costs for diagnostic time and potential related repairs, as well as the variability of labor rates based on location and service provider. To obtain a more accurate estimate, it's recommended to consult with local auto repair shops or dealerships.
