Lexus GS Oxygen Sensor Issue

My 2020 Lexus GS gasoline with 155584 km has the check engine light on and a diagnostic shows an oxygen sensor error. Fuel consumption is also higher. Could the cable or plug connection be defective? Has anyone else experienced this?

I had a similar issue with my GS. Is it specific to one of the sensors? Usually, exhaust system issues trigger the check engine light. Any noticeable impact on performance or the catalytic converter?

The error code points towards the aged oxygen sensor, but doesn't specify which one. I haven't noticed any performance issues. Could this still be related to the catalytic converter, even without performance loss?

My oxygen sensor issue led to catalytic converter problems later. To avoid further damage, have it inspected. Given the stored error and increased fuel consumption, it's worth checking soon.

I'll schedule a workshop appointment to check the oxygen sensor and connection. The repair cost 95€. Thanks for the help.
