P0137 2019 Honda CR-V Code - Secondary Heated Oxygen Sensor 2 Circuit Low Voltage
Quick Answer
The P0137 diagnostic trouble code (DTC) for a 2019 Honda CR-V refers to an issue with the Secondary Heated Oxygen Sensor 2 Circuit, indicating that the sensor is not operating within the expected voltage range. Common causes include Faulty Oxygen Sensor: The most common cause of a P0137 code is a malfunctioning secondary heated oxygen sensor, Wiring Issues: Damaged or corroded wiring connecting the sensor to the ECM can cause a low voltage reading, Exhaust System Leaks: Leaks in the exhaust system before the oxygen sensor can affect its operation and trigger the code. 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 P0137 2019 Honda CR-V Description
The P0137 diagnostic trouble code (DTC) for a 2019 Honda CR-V refers to an issue with the Secondary Heated Oxygen Sensor 2 Circuit, indicating that the sensor is not operating within the expected voltage range. The secondary heated oxygen sensor, also known as the downstream oxygen sensor, is responsible for monitoring the exhaust gases after they have passed through the catalytic converter. This sensor measures the oxygen levels in the exhaust gases and sends this data to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion.
Common Causes of P0137 2019 Honda CR-V
- Faulty Oxygen Sensor: The most common cause of a P0137 code is a malfunctioning secondary heated oxygen sensor.
- Wiring Issues: Damaged or corroded wiring connecting the sensor to the ECM can cause a low voltage reading.
- Exhaust System Leaks: Leaks in the exhaust system before the oxygen sensor can affect its operation and trigger the code.
- Engine Misfire: A misfiring engine can affect the oxygen sensor's readings and lead to a P0137 code.
- Faulty ECM: In rare cases, a malfunctioning engine control module may be the cause of the low voltage reading from the oxygen sensor.
Symptoms of P0137 2019 Honda CR-V
- Check Engine Light: The most common symptom associated with a P0137 code is the illumination of the check engine light on the dashboard.
- Poor Fuel Economy: A malfunctioning oxygen sensor can cause the engine to run rich or lean, leading to decreased fuel efficiency.
- Rough Idling: The engine may exhibit rough idling or hesitation when the oxygen sensor is not functioning correctly.
- Failed Emissions Test: A faulty oxygen sensor can cause the vehicle to fail emissions tests due to increased emissions levels.
- Reduced Engine Performance: The engine may feel sluggish or have reduced power output when the oxygen sensor is not operating within the correct voltage range.
How to Fix P0137 2019 Honda CR-V
- Diagnose the Issue: Use an OBD-II scanner to retrieve the specific trouble code and determine if the secondary heated oxygen sensor 2 is the cause of the low voltage reading.
- Inspect Wiring: Check the wiring harness connecting the sensor to the ECM for any damage, corrosion, or loose connections.
- Replace Oxygen Sensor: If the sensor is confirmed to be faulty, replace it with a new sensor compatible with the 2019 Honda CR-V.
- Clear Codes: After making the necessary repairs, clear the trouble codes stored in the ECM to reset the check engine light.
- Test Drive: Take the vehicle for a test drive to ensure that the issue has been resolved and the sensor is now operating within the expected voltage range.
