Genesis Oxygen Sensor Issue

My 2016 Hyundai Genesis gasoline engine is showing an oxygen sensor error, and the check engine light is on. I've also noticed increased fuel consumption. I'm wondering if it's a defective cable or plug connection. Anyone else seen this?

An aged oxygen sensor could cause those symptoms. Check the sensor's wiring harness for damage or corrosion. Air-fuel ratio issues will flag the CEL.

Thanks. Is there a specific area or pin on the wiring harness that's known to be problematic on this model?

I can't pinpoint a specific pin issue, but a damaged connection definitely fits the symptoms. To be safe, consulting a workshop seems appropriate.

Thanks for the help. It was a defective oxygen sensor cable, as suspected. The repair cost 95€.
