I am reviewing a Denso oxygen sensor 234-9025 that I installed on my 4 cylinder 1999 Honda Accord. I warmed up my engine and than let it cool for about 10 minutes. The location of the oxygen sensor on this model is just perfect. You do not need any special tools or arrangements. A 22 millimeter open end wrench is all you need to remove the old sensor. The new sensor comes with the copper based anti-seize compound, which is helpful. I gave the product four stars because I had very hard times to plug the connector to the existing harness. The connector just did not want to go in. I played and played with it for quite some time until it finally went in. Other than that the installation was uneventful. I have had on the new sensor more than five hundred miles and there is no check engine line.Read full review
