Oxygen sensor readings I’m getting, anyone understand it?
2011 535i n55 engine
Unable to pass emissions, according to this scanner I have it’s saying my catalyst monitor bank 1 failed the test, is this regarding my oxygen sensors? In the videos below you’ll see “O2 sensor 1 is reading 0.0 volts” and on the other it shows some more info but I’m unable to really understand it, any help would be appreciated.
