Is the toyota 89467-48011 part number stamped on sensor body, which is a denso, the same sensor as 89467-41011.
Many sites seem to suggest that it is., both being Denso 234-9009.
The reason I am asking is that I can buy the first for £186.00 + vat, from the lexus dealer, whereas the second from the toyota dealer is only £135 + vat.
If anyone can help I would be obliged. Rock Auto in your part of the world lists the 41011 for my vehicle but with (Calif) after the part number, which Im thopught maybe just a local thing.
Pls help if you can.
thks Malcolm

I had same problem with my 99 RX300. Did research on what can I do to fix it with minimum $$$ contribution as I didn't want to spend $160-$130 for damn sensor( I am not talking about going to dealership and spend $$$$$ for no reason) What I found is Denso O2 sensor, not air flow sensor everybody talking about. My original AF sensor was 89467-48011 and I installed Denso 234-9009 O2 instead of it for $50 only, on ebay!!!!! Reset check engine light, disconnect battery, take the old one out and put the new on in, connect the battery, Done. Drive 50-60 miles and go to emmission test. Hope this information will help someone.

Denso 234-9009 is a A/F sensor not an 02 sensor. A/F sensor A/F sensor
You can not mix A/F and 02 sensors. They do not operate in the same manner and are not interchangable.
Glad you were able to get one cheaper than most, but dealerships are not always higher in price, if you know the right person to ask.

Good OEM quality sensors can be sourced from here..

NGK Spark plug, NGK Spark Plug wire, NGK Platinum Spark plug for High Performance and Racing.

I have used the NGK ones and they hold up pretty well. Well past the 80K EOL (End of Life) mark!!!
