2002 Chevy Suburban 1500, O2 sensor problems

2002 Chevy Suburban 1500, i've got three O2 sensor codes: P0137 (bank 1 sensor 2), P0252 (bank 2, sensor 1), P0157 (bank 2, sensor 2) - all say: O2 Circuit, low voltage. What is causing this and what do i need to do about it? Any help appreciated.

    I have seen dirty MAF (mass air flow sensors) throw multiple o2 trouble codes, do you know how to clean the MAF?

P0157 02 Sensor Circuit Low Voltage (Bank 2 Sensor 2)

P0137 02 Sensor Circuit Low Voltage (Bank I Sensor 2)

There is something that could be making the air and fuel mixture incorrect causing these codes. It don't necessarily mean you need new O2 sensors.

SOURCE: CHECK ENGINE LIGHT IS ON, GOT CODES P0157 2 TIMES,

the bank 2 sensor2 is used to check that your catylitic converter is working on that side of the exhaust. without seeing the car and doing sensor tests, it would be a gamble to say replace the sensor. so you can replace it and see what happens or take it to your favorite shop for further diagnosis

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.

    Codes P0131, P0137, P0341, and B1218. Code P0131 and P0137 were listed twice. This is for a 2000 chevy venture. I already spent $400. 2 years ago for emissions


    HI ghosthunter6 codes P0131&P0137&P0341 indicative of having electrical short .
    P0131 Front Heated Oxygen Sensor Bank 1 harness is open or shorted .
    P0137 Rear Heated Oxygen Sensor Bank 1 harness is open or shorted .
    P0341 Camshaft position sensor harness or connectors (The sensor circuit is open or shorted) .
    code B1218 horn relay coil circuit short to voltage battery .
    IT could be cousin problem with other sensors .
    First replace horn relay and clear E C M codes
    IF problem and codes P0131&P0137 come back you need o2 sensors .put I don't thank so.
    YOU MUST REPLACE HORN RELAY .OK

    good luck

    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

    P0137 o2 circuit low voltage bank 1 sensor 2 --o2 sensor after the cat converter -check for faulty o2 sensor -short or open circuit exhaust leak near sensor or plugged cat converter ----P0171 and P0174 -system too lean bank 1--and system too lean bank 2 they are usually from the same problem which can be caused from the o2 problem but check ur maf sensor connections and or clean if necessary[carb cleaner] vacuum leak downstream from maf sensor also inspect pcv lines

    2002 Alero check Engine light Codes P0132, P0137


    Code P0132 is O2 sensor voltage high bank1 sensor 1, P0137 is O2 sensor voltage low bank 1 sensor 2, P1189 indicates a fuel control problem bank 1. It could be either the O2 sensors or a convertor. Could also be intake manifold gaskets. GM had a lot of problems with the lower intake gaskets leaking on the 3.1 and 3.4 engines that was linked to their Dexcool coolant. In fact they just lost a class action lawsuit about it. check with the dealer and see if the intake problem has been taken care of. Hope this helps.
