Rx300 - Oxygen Sensor - Part 89465-48180

[twinkle]

Greetings good people, I need to change my bank 1 sensor 2 oxygen sensor and I was wondering what Denso oxygen sensor to buy? I have called about five Lexus dealerships and quotes are between £170 and £250 per sensor. Three dealerships confirmed the part number as 89465-48180, while two said they cannot divulge part numbers.

A while back, I read on one Lexus forum that some RX300 owners were having luck with the Denso 0243 oxygen sensor. I just wondered if this sensor will actually do? If not, I would appreciate information on the right Denso sensor.

Thanking you all in anticipation of your helpful responses.

That part code is correct if you have a generation 2 vehicle with a 5 speed transmission?

Euro car parts list a Denso direct fit for £94. The rear sensor isn't anything special, unlike the front ones, so ones not directly listed as compatible should work, it is just lead length, connector, and any rubber grommet that needs to match.

An alternative would be to import from the US. I believe the RX330 uses the same sensor as the RX300 (the RX300 was never available in the US).

Please be aware that a suspected rear sensor or more often than not actually another issue, such as a front sensor, exhaust air leak or Cat. convertor problem. What error code(s) are being triggered?
