A few wild guesses . I think most O2 sensors now have electric heaters .
I would first check the fuses & see if any are blown . If so , visually check the wiring for damage . If damaged , I would unplug all of them , replace fuse / fuses U see if the fuses held . If so , I would check voltage at the connector of 1 & if voltage ( on the larger 2 wires ) is good , plug it back in . See if it blows the fuse again . Repeat for all of the sensors .
If no fuses have blown , I would clear codes and drive it .
Or , go to YouTube and look up South Main Auto channel . Look for a video of Eric O. testing O2 sensors .
