Expensive but this one worked when the cheaper Kwiksen didn't.

It worked as expected but the first Kwiksen test I tried didn't work. Same part number link but this is the OEM version and the Kwiksen is the aftermarket variant.

This Denso sensor is quite expensive for an O2 sensor but it works so I guess you get what you pay for.

Pros
  • Air to Fuel Ratio
Cons
  • Available in White only

Do it yourself and save!

I got my first CEL on my 2004 Honda Accord (190,000 miles) and it ended up with P1157 which is an upstream O2 sensor failure (bank 1 sensor 1). The mechanic called 250 for the repair and I saw that online it seemed easy so I installed it myself. This is an OEM O2 sensor that Honda uses. It looked the same and was exactly the same length. The product contains an anti-seize lubricant that should be applied to the threads when installing a new sensor. A low profile O2 sensor socket should be used…
