Review on 🌬️ 234-4137 Denso Oxygen Sensor by Jonathan Lamp

great part. I did some research and for my Lexus (Toyota) everyone said I should use this Denso part. Good price. Look on YouTube or elsewhere how to change this part. It seems simple, but the plug goes into the car. Mine was under the driver's seat. I would never look there! With some effort I was able to use the connector instead of cutting the wires. take your time and do it right. Note: I have seen information that replacing this sensor can eliminate the "Bad Catalytic Converter" code my car was giving out. and so it went for two days. Luckily I was able to pass the emissions test, after which the CEL turned on again. So, fast forward to December (since August), I finally switched cat (landed directly on Walker 16130) and my CEL finally shut down. This sensor still works!
