The part numbers for the oxygen sensors for 99-00 GS300 on oxygensensors.com are incorrect. I ordered oxygen sensors for bank 1 sensors 1 and 2. Each costing 100+ dollars. I installed bank 1 sensor 1 and took my GS to Lexus to have the EUC reset and to make sure that was the only problem making my check engine light come on. I was told that the sensor I installed was not working correctly. I wasnt sure if they were telling me the truth since I didnt buy the sensor from Lexus. You know how that goes. I was also told that I needed to replace bank 1 sensor 2. I ordered that sensor from oxygensensors.com as well. I recived it today and went to install it and noticed that the numbers on the sensor didnt match the one I had just taken off my car. I did a search on google to see if these numbers checked out or cross refernced but instead I found a thread on CL where other people were having the same problem I'm having getting the wrong sensors from oxygensensors.com. I called up oxygensensors.com and was questioned as to weather or not I knew what I was doing. I worked on cars for a living longer than oxygensensos.com has been around. I told him that the numbers on the sensor its self did not match up. He told me that the numbers on the sensor had nothing to do with a part number, that they were just a referance as to where they were made. I know better than that so I looked up the numbers on Denso's website and found the correct part numbers. I hope I get this all straightened out. I already put one of the sensors on the car so so much for getting that money back or exchanging the part. Now I see why there sensors are so cheap. You end up paying 200+ anyway....

the correct Denso part numbers are:

(1,2,3 precat) Bank 1 Sensor 1: 234-4048

(1,2,3 postcat) Bank 1 Sensor 2: 234-4626

(4,5,6 precat) Bank 2 Sensor 1: 234-4630

(4,5,6 postcat) Bank 2 Sensor 2: 234-4603


oxygensensors.com has part numbers

(1,2,3 precat) Bank 1 Sensor 1: 234-4048

(1,2,3 postcat) Bank 1 Sensor 2: 234-4622

(4,5,6 precat) Bank 2 Sensor 1: 234-4626

(4,5,6 postcat) Bank 2 Sensor 2: 234-4603

This is good to know. My o2 sensors may be on the way out soon. Thanks for the heads up!

As an update, it looks like oxygensensors.com has updated their part numbers. Last week I purchased a sensor for bank 1 sensor 2, Denso part number 234-4626, and the sensor came in a bag labeled 234-4626. I put it in after making sure that their website says that 234-4626 is for 1,2,3 post cat and the check engine light has gone off. So it looks like they have corrected the problem.

I used a universal Bosch for 60 bucks. Works great. Wiring was extremely easy.
