SOURCE: Check Engine light with Po131 o2 circuit low voltage sensor 1 bank 1 reading, what does that mean?

- Front Heated Oxygen Sensor Bank 1 harness is open or shorted
- Front Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Faulty Front Heated Oxygen Sensor Bank 1
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Exhaust gas leaks

Replacing the O2 Sensor 1 usually takes care of the problem

The front heated oxygen sensor (or O2 sensor 1) is placed into the exhaust manifold. It detects the amount of oxygen in the exhaust gas compared to the outside air. The heated oxygen sensor 1 has a closed-end tube made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. The heated oxygen sensor 1 signal is sent to the Engine Control Module (ECM). The ECM adjusts the injection pulse duration to achieve the ideal air-fuel ratio. The ideal air-fuel ratio occurs near the radical change from 1V to 0V.

P0137 is an O2 sensor low voltage code. bank 1 sensor 2. This could cause a rough start. The sensor that needs replaced is on the drivers side, after the catalytic converter

Check engine code p0137


P0137 - Oxygen (o2) sensor circuit low voltage (Bank 1 sensor 2)
If you have more than one (1) sensor on Bank 1 then it will be the rear sensor. Change the o2 sensor. You may also want to check the following:
  • Repair exhaust leak near the rear sensor (if leak is found)
  • Check for restriction in catalyst and replace as necessary
  • Repair short, open, or high resistance on o2 signal circuit

  • Most likely you will just need to replace the sensor. Hope this helps you.

    From what I can find in my book - they are (generic code)
    P 0700 Transmission Control System Malfunction
    P 0133 O2 Sensor Circuit Slow Response (Bank 1 Sensor 1)
    P 0137 O2 Sensor Cicuit Low Voltage (Bank 1 Sensor 2)
    P 0131 O2 Sensor Circuit Low Voltage (Bank 1 Sensor)
    P 0171 System Too Lean (Bank 1)
    Could not find these codes in the GM section - that is why I went with the Generic codes

    I have code p0137 coming up on my 2003 jeep grand cherokee laredo what does the code mean?


    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
