    P0136 = O2 circuit [Bank1, sensor 2]
    P0137 = O2 circuit low voltage [Bank1, sensor2]

    For the P0137 code, my scanner had….
    Fuel Sys 1 CL
    Calc LOAD(%) 7.8
    ECT(F) 194
    STFT B1 (%) 0
    LTFT B1 (%) -25.0

    I replaced the downstream (under car) O2 sensor with a genuine, new AC Delco part about 2 years ago after I was getting the P0137 code. A few months ago I started getting P0136 and P0137 codes. Could that sensor have gone bad that fast ? I have been clearing the codes in hopes that the long highway drives I have been doing would clear things up. Fat Chance !! Any ideas on how to troubleshoot what’s going on or should I just buy another sensor and put it in…. I don’t recall ever changing the upstream sensor. Could that have anything to do with it ? Thanks…

    The front o2 sensor won't have anything to do with a low voltage code on the rear sensor.

    I'd check fuses and the wiring on the harness. If that checks out then it's possible the sensor is at fault.

    Same, check fuses and wires, and be sure to put some di-electric grease inside the plug when you're re-connecting the harness.

    Alternate option would be to put an extension before the sensor to reduce the chance of fouling. ZZP and many other place have them.

    Thanks guys. I will check all the wiring and the plug at the O2 sensor. I will use some Di-electric grease on it too.
    I'll chek back in after I do those things, but it may be awhile with this damn Chinese Virus bs going on.....
    What a nightmare scenario for all of us..... I am hoping it's more media hyoe than reality for 90% of the country and world !
