P0137 2020 Honda CR-V Code - Secondary Heated Oxygen Sensor 2 Circuit Low Voltage

Quick Answer

The Secondary Heated Oxygen Sensor (Secondary HO2S or Sensor 2) is a component in your vehicle's exhaust system that detects oxygen levels in the exhaust gas. Common causes include Faulty Secondary Heated Oxygen Sensor 2, Secondary Heated Oxygen Sensor 2 harness is open or shorted, Secondary Heated Oxygen Sensor 2 circuit poor electrical connection. 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 2020 Honda CR-V Description

The Secondary Heated Oxygen Sensor (Secondary HO2S or Sensor 2) is a component in your vehicle's exhaust system that detects oxygen levels in the exhaust gas. It then converts this information into electrical signals. If the sensor's output voltage remains steady at a specified value for a certain duration, the vehicle's onboard computer, known as the Powertrain Control Module (PCM), identifies this as a potential problem. In response, the PCM stores a Diagnostic Trouble Code (DTC) to indicate the issue for diagnostic purposes. This system helps ensure the vehicle's emissions control system is functioning correctly, contributing to optimal engine performance and emissions reduction.

Frequently Asked Questions about P0137 2020 Honda CR-V Code

What does the OBDII code P0137 mean for a 2020 Honda CR-V?

P0137 indicates that the secondary heated oxygen sensor (HO2S 2) is experiencing a low voltage condition, suggesting that it may be malfunctioning or that there is an issue with the circuit.

What are the common symptoms associated with the P0137 code?

Common symptoms include poor fuel economy, increased emissions, a rough idle, and the check engine light illuminating on the dashboard.

What could cause the P0137 code to trigger in my Honda CR-V?

Causes can include a faulty secondary oxygen sensor, damaged wiring or connectors in the sensor circuit, exhaust leaks, or issues with the vehicle's engine control unit (ECU).

How can I diagnose the issue related to code P0137?

To diagnose P0137, you can use an OBDII scanner to confirm the code, inspect the wiring and connectors for damage, test the secondary oxygen sensor's voltage output, and check for exhaust leaks.

What is the typical repair for a P0137 code?

Typical repairs may involve replacing the faulty secondary heated oxygen sensor, repairing any damaged wiring or connectors, or resolving any exhaust leaks present in the system.

Can I drive my Honda CR-V with the P0137 code?

While it may be possible to drive the vehicle, it is not recommended, as it can lead to decreased fuel efficiency, increased emissions, and potential damage to the catalytic converter over time.

How much does it cost to fix the P0137 code?

Repair costs can vary widely depending on the cause; replacing the oxygen sensor typically ranges from $100 to $300, while more extensive repairs like wiring fixes may cost more.

Will clearing the code P0137 fix the problem?

Clearing the code may temporarily turn off the check engine light, but it will not fix the underlying issue. The code will likely return if the problem is not resolved.

Is there a risk of damaging other components if I ignore the P0137 code?
