Oxygen Sensor Issue on 2022 Lexus NX

Hey, I have a 2022 Lexus NX with a gasoline engine. Recently, the check engine light came on, and I've noticed my fuel consumption is way up. Plugged in an OBD scanner, and it's showing an oxygen sensor heater failure. I've checked for any obvious loose connections, but everything seems fine. Any ideas?

A 2022 Lexus NX owner is experiencing a check engine light and increased fuel consumption, with an OBD scanner indicating an oxygen sensor heater failure. Despite checking for loose connections, the issue persists. A similar case suggested that the problem might be due to a defective cable or plug connection, and a professional inspection is recommended to resolve the issue.

Interesting. I had a similar issue with my old Opel Astra – different car, same headache. Same symptoms: check engine light, increased fuel consumption, and the OBD scanner pointed to the oxygen sensor. Is the error permanently stored or does it disappear after a while?

Good to know I'm not alone. The error is permanently stored in the error memory. Is that the same you encountered?

Yes, exactly. The error remained permanently stored. For me, it turned out to be a defective cable or plug connection, as the diagnostic indicated. I would highly recommend to go to the workshop to have it checked by a professional. I got a bill of 95€ in the end.

Thanks a lot for sharing your experience! Will do. Guess I'll book it in for a proper checkup. I appreciate the help!
