Review on Denso 234-9025 Air Fuel Ratio Sensor: Precision Measuring for Optimal Combustion by John Arsov

I bought this for my 1999 Honda Accord ULEV 4 cylinder engine and it has been running great for a few years now. The reason I replaced the O2 sensor was because it gave an error message which caused the check engine light to come on. A replacement I got from a local parts store didn't solve the problem and then I found this statement that it was a ULEV engine and it worked fine for years. I recommend using the O2 sensor connector or you will have a miserable life trying to remove and reinstall the part. Highly recommended!
