Easy install. About 15 minutes extra required to adapt sensor to OEM harness but worth cost savings!

Works to specification in 1997 CRV at post convertor position. I had previously purchased another brand that did not work in this application due to the sensor heater resistance being too low.

The same brand as the removed O2 sensor. Fixed the dtc 420 fault. I do not trust splices,which was provided so I soldered it but after a long thought I realize that the splice would have worked as good.


Excellant Replacement Part by Lexowner, November 6, 2009

Excellent OEM replacement for a 02 lexus IS300. Fits B1S1 and B1S2 applications. No more check engine light problems due to a p0420, p0430 cat flow problem. No more problems and I couldn't be more pleased with the price. Generally cheaper and more reliable than Ebay. New sensor in denso box is what i recieved and thats what you want for a lexus. OEM name brand parts. These sensors will do the job.

By far the easyest thing of the project to install. The splicing took the longest, but was a piece of cake. Everything I needed was in the box.

Be ready to splice the wires in because you have to use the old plug off your vehicle. You will also need a heat gun as there are heat shrink shrouds for the wires. Having said that, it went together pretty quickly - I was expecting to be able to just plug it in...
