How To Fix P0137 Code?

How do I fix code p0137?

What repairs can fix the P0137 code?

  • Replacing the O2 sensor for bank 1 sensor 2.
  • Repairing or replacing the wiring or connection to the O2 sensor for bank 1 sensor 2.
  • Repairing exhaust leaks before the sensor.

What causes a p0137 code?

Code P0137 is triggered when the powertrain computer or PCM determines that the rear oxygen sensor voltage remained below 400 millivolts for more than twenty seconds (varies with vehicle make and model) or that the air fuel ratio sensor remained in a lean-biased mode for too long (varies with vehicle make and model).

What causes low voltage on o2 sensor?

The low voltage signal means lean air fuel mixture, or too much oxygen and too little fuel. The code P0131 is set when the signal voltage from the front O2 sensor is stuck low. In modern cars, the air fuel ratio sensor (A/F sensor) is used instead of the O2 sensor, but it’s also often referred to as a front O2 sensor.

What does it mean bank 1 sensor 2?

The front oxygen sensor before the catalytic converter is usually called ‘upstream’ or Sensor 1. The rear oxygen sensor installed after the catalytic converter is called ‘downstream’ or Sensor 2. A typical in-line 4-cylinder engine has only one bank (Bank 1). “Bank 1, Sensor 2” is the rear oxygen sensor.

Which 02 sensor is bank 1 sensor 2?

Bank 1 Sensor 2 = This O2 sensor is located right after the catalytic converter, on the side with the Cylinder #1 that is Bank 1. Bank 2 Sensor 1 = This O2 sensor is located right before the catalytic converter, on the side with the Cylinder #2 that is Bank 2.

Which is bank 1 sensor 2?

The front oxygen sensor before the catalytic converter is usually called ‘upstream’ or Sensor 1. The rear oxygen sensor installed after the catalytic converter is called ‘downstream’ or Sensor 2. A typical in-line 4-cylinder engine has only one bank (Bank 1).

How much do o2 sensors cost to replace?

A faulty oxygen sensor will cause you to fail an emissions test. A brand new replacement oxygen sensor can cost you from $20 to $100, depending on the make and year of your car. Taking your car to a mechanic to fix the issue can cost up to $200. Though, this depends on the type of car and the rates of the mechanic.

How do you fix code p0037?

What repairs can fix the P0037 code?

  1. Have a certified technician verify the code with a scanner. Reset the fault codes and perform a road test.
  2. If the P0037 code returns, then follow the test procedure. It can have several problems, but wiring being damaged by excessive heat from the exhaust is most common.

Why are o2 sensors heated?

The oxygen sensor must be hot (about 600 degrees or higher) before it will start to generate a voltage signal, so many oxygen sensors have a small heating element inside to help them reach operating temperature more quickly.

Where is the oxygen sensor located?

Oxygen sensors are located within the exhaust stream, there is at least one oxygen sensor located before the catalytic converter and typically one in each exhaust manifold. Depending on the exhaust system design there may be one or two located after the catalytic converter to monitor its effectiveness.

What voltage should downstream o2 sensor read?

around 0.45 volts

Can you bypass the o2 sensor?

Bypassing an oxygen sensor–also called an O2 sensor–can only be done using a dummy O2 sensor. Oxygen sensors are part of the vehicle’s emissions control system and it may or may not be legal to replace the O2 sensor with a dummy sensor.
