In o2 hell

Hey guys, I’m new here and I’m turning to you after my complete confusion I have a 2004 3.4 tundra automatic I get codes P0 031 from a cheap scanner and code P2238 from a snap on scanner both of which I have determined to be the heater circuit on the bank 1 o2 sensor, I’m confirming the sensor is good. I’m trying to find a wiring diagram to the ECM from bank 102 sensor. Or if you’ve ran into the same problem, can anyone help
