You could try taking it out and cleaning it, but you might have to replace it.

Also check the wiring from it for breaks/chafeing, and check the connectors for corrosion.

P0137 issues changed out manifold new sensor new cat converter. Still have p0137. HELP!


Essentially the same as P0136, P0137 refers to the second oxygen sensor on Bank 1. P0137 means the O2 oxygen sensor's voltage remained low for longer than 2 minutes. This, is interpreted by the ECM as a low voltage condition and sets the MIL. Bank 1 Sensor 2 is located to the rear of the catalytic converter and should produce an output signal relative to oxygen storage capacity of the catalytic converter. This rear (sensor 2) sensor is less active than the signal produced by the front sensor. However, if the ECM senses the sensor is inactive, this code will set.

There may be no visible symptoms to the driver, other than the MIL (Check Engine / Service Engine Soon) illumination.

A code P0137 may mean that one or more of the following has happened:
Faulty o2 sensor Exhaust leak near the rear sensor
Plugged catalyst
Short to voltage on O2 signal circuit
High resistance or open on O2 signal circuit

Hope helps; your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

Code PO133 Keeps Coming Up


I really hate to state the obvious, but if the code "keeps" coming up it is because the code keeps not getting properly diagnosed and repaired.

The generic description for code P0133 is "Oxygen Sensor Slow Response Bank 1 Sensor 1"
This could be due to an oxygen sensor that is just plain worn out and chemically inactive. However, The most likely cause is contamination of the oxygen sensor. (especially if the sensor has been replaced and the code still returns) Contamination from oil or antifreeze is the most common cause of this code. Oil gets into the exhaust due to bad valve seals or piston rings. Antifreeze gets into the exhaust due to blown head gaskets or cracked heads. It can also be contamination from misuse of RTV sealants or aftermarket fuel additives. In any case, replacement of the sensor alone will most likely only result in a repeat repair. The source of contamination must be identified and corrected for the repair to be successful.

Code p137 could it be the oxygen sensor


P0137 refers to the second oxygen sensor on the car. It means the O2 oxygen sensor's voltage remained low for longer than 2 minutes. Bank 1 Sensor 2 is located to the rear of the catalytic converter. This rear sensor's signal is less active than the signal produced by the sensor closer to the manifold. However, if the car senses the sensor is inactive, this will set off the check engine light as well.

Replace that second sensor and it should cure your problem.

I hope this is helpful, if you need more help. Please feel free to re-post at FixYa for all you automotive needs.

P0137 - Oxygen O2 Sensor Circuit Low Voltage (Bank 1, Sensor 2)

Essentially the same as P0136, P0137 refers to the second oxygen sensor on Bank 1. P0137 means the O2 oxygen sensor's voltage remained low for longer than 2 minutes. This, is interpreted by the ECM as a low voltage condition and sets the MIL. Bank 1 Sensor 2 is located to the rear of the catalytic converter and should produce an output signal relative to oxygen storage capacity of the catalytic converter. This rear (sensor 2) sensor is less active than the signal produced by the front sensor. However, if the ECM senses the sensor is inactive, this code will set.

Symptoms: There may be no visible symptoms to the driver, other than the MIL (Check Engine / Service Engine Soon) illumination.

Causes: A code P0137 may mean that one or more of the following has happened:
* Faulty o2 sensor Exhaust leak near the rear sensor
* Plugged catalyst
* Short to voltage on O2 signal circuit
* High resistance or open on O2 signal circuit

Possible Solutions:
* Replace faulty sensor
* Repair exhaust leak near the rear sensor
* Check for restriction in catalyst and replace as necessary
* Repair short, open, or high resistance on o2 signal circuit

I have a 1996 honda passport V6, the car was scanned and found code p0134. the car runs but after a few minutes of warming the car stalls and backfires runs terrible what can cause those type of problems


This code refers to the front oxygen sensor on Bank 1. Basically the oxygen sensor is inactive.

DTC P0134 - 02 Sensor Circuit No Activity Detected (Bank I Sensor 1)

The powertrain control module (PCM) provides a baseline voltage of about 450 mV on the oxygen sensor signal circuit. When cold, the PCM detects the the internal resistance of the sensor is high. As the sensor warms up the resistance is lowered and it starts producing voltage based on the oxygen content in the exhaust. When the PCM determines that the time it took for the sensor to warm up is greater than one minute or that the voltage is inactive (not reading outside 391-491 mV it views the sensor as inactive or open and sets the P0134 code.

Potential Symptoms: One or more of the following may occur:
* Check engine light illumination
* Poorly running/engine missing
* Blowing black smoke
* Poor fuel economy
* Dying, stuttering

Causes: A code P0134 may mean that one or more of the following has happened:
* Bad O2 (oxygen) sensor
* Bad heater circuit in the O2 sensor
* Wiring or connector to the sensor frayed / broken
* Blown heater circuit fuse
* Holes in the exhaust system
* PCM failure

Possible Solutions: The most common fix is to replace the oxygen sensor. But that doesn't rule out the possibility of:
* Rusted exhaust pipe
* Inspect wiring & connector(s) for problems
* Excessive amperage blowing heater fuse (still requires replacement of sensor but also replacement of blown fuse)
* Replace PCM (only as last resort after all other possibilities are covered.


Hope helps (remember rated and comment this).
