P0137 Honda 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.

Frequently Asked Questions about P0137 Honda Code
1. What does the OBDII code P0137 mean on a Honda?
P0137 indicates that the Secondary Heated Oxygen Sensor 2 (typically located downstream of the catalytic converter) is detecting a low voltage signal, which may suggest an issue with the sensor or the fuel system.
2. What are the symptoms of a P0137 code on a Honda?
Common symptoms include an illuminated check engine light, decreased fuel efficiency, rough idling, possible engine hesitation, or no noticeable symptoms at all.
3. What causes the P0137 code on a Honda?
Possible causes include a faulty oxygen sensor, damaged wiring or connectors, an exhaust leak, or a problem with the engine control unit (ECU).
4. Can a bad catalytic converter trigger a P0137 code on a Honda?
Yes, a failing catalytic converter can cause improper exhaust flow, leading to low voltage readings from the downstream oxygen sensor.
5. How can I fix a P0137 code on my Honda?
Start by checking for damaged wiring or loose connectors near the oxygen sensor. Replace the oxygen sensor if needed, and inspect the exhaust system for leaks or damage.
6. Is driving with a P0137 code on a Honda safe?
While the car may remain drivable, ignoring the code can lead to reduced fuel efficiency and potential damage to other components, such as the catalytic converter.
7. How do I test the oxygen sensor for a P0137 code on a Honda?
Use a multimeter to check the sensor's resistance and voltage output. Compare the readings with the manufacturer’s specifications to determine if the sensor is functioning correctly.
8. Can a dirty air filter cause a P0137 code on a Honda?
A dirty air filter is unlikely to directly cause a P0137 code, but it can impact fuel mixture and engine performance, which might indirectly affect oxygen sensor readings.
9. Do I need to replace the oxygen sensor if I get a P0137 code on a Honda?
Not necessarily. First, inspect the wiring, connectors, and exhaust system. If those are in good condition, the oxygen sensor may need replacement.
10. Will clearing the P0137 code on my Honda fix the issue?
Clearing the code will turn off the check engine light temporarily, but the issue will reoccur if the underlying problem isn’t resolved.

2005 honda crv & 2005 honda lx. Both have 2.4L 4cyl. Replaced rear and front o2 sensor on both cars. Code is still there.
P0139 for the LX. Also both still have p0325knock sensor, replaced those as well... -
Do you have any exhaust leaks?
Other than the sensors and exhaust leaks, I have not seen any other components triggering the P0137 code. The P0139, could also be cause for "Intake" leaks.If no leaks are found, then you may have a problem with the Engine Control Module (ECM), it's not common, but I have seen a few.

I have the same vehicle and same code but m7y fuel consumption
is 260ks to 40 leterse
