Code P0137 2018 Honda CR-V Description
The P0137 diagnostic trouble code (DTC) for a 2018 Honda CR-V refers to the Secondary Heated Oxygen Sensor 2 Circuit Low Voltage. This code indicates that the oxygen sensor located after the catalytic converter is detecting a lower than expected voltage signal. The oxygen sensor plays a crucial role in monitoring the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion.
Common Causes of P0137 2018 Honda CR-V
- Faulty secondary heated oxygen sensor
- Damaged wiring or connectors
- Exhaust leaks near the oxygen sensor
- Issues with the engine control module (ECM)
- Contaminated or deteriorated oxygen sensor
Symptoms of P0137 2018 Honda CR-V
- Decreased fuel efficiency
- Rough idling or stalling
- Engine hesitation during acceleration
- Illuminated check engine light
- Failed emissions test
How to Fix P0137 2018 Honda CR-V
- Begin by diagnosing the issue using a scan tool to confirm the P0137 code and pinpoint the exact cause.
- Inspect the secondary heated oxygen sensor and its wiring for any visible damage or corrosion.
- Test the oxygen sensor's voltage output to determine if it is functioning within specifications.
- Replace the secondary heated oxygen sensor if it is found to be faulty, ensuring proper installation and connection.
- Clear the DTC and perform a test drive to verify that the issue has been resolved.
Cost to Fix P0137 2018 Honda CR-V
The typical repair costs for addressing a P0137 code on a 2018 Honda CR-V can range from $150 to $400, including parts and labor.
