    02 is working doing it,s job just the heater built into the 02 sensor is not.
    It is a emissions part of it . Warms 02 up faster so it can start reading faster.
    Here is a link of what maybe wrong. I,am having this problem also . I have a good ground but not getting the voltage to run heater .
    Probably a bad wire in the harness somewhere. Or maybe need to get a oem 02 i installed a bosh but some ay no get a oem will not have this trouble . We will see .
    Here is a link with things to check. www.engine-codes.com/p0036.html

    I'm having the same problem. I have changed my O2 sensor twice and I think its in the harness. I'm searching trying to find out about a wiring harness.
