About Denso 234-4018 Oxygen Sensor
Overall Feedback:
89% positive
84% praised the accurate readings
After replacing the O2 sensors, my mileage improved and I was able to pass emissions. It also fixed the P0420 and P0430 codes, saving me from having to replace my catalytic converter.
After installing the Denso oxygen sensor, the code was gone and my motor was running smoothly.
85% liked the compatibility
The replacement oxygen sensor is an exact match for the factory AC Delco part on my old 2001 Buick Park Avenue.
86% found it easy to install
The installation process was quick and everything matched up well.
Installation was quick and easy.
I found it easier to install the oxygen sensors than I thought. I only needed a special socket and a short breaker bar, but all the old sensors came out nicely. The threads were in great shape despite the outside looking like a rusted nightmare.
