kimo... Did you ever get hold of a 2001 RX300 service manual? thx Russ Did you get 2001 manual? Please post. Thanks.

How many mile is on yours? There are three sensors on my 2001, two air fuel ratio and one O2. the air fuel ratio sensor is last about 90K, however, the one in the back of fire wall engine is usually goes off around 80K because the heat, the one in front is around 100K. I never heard anyone has problem with O2. Anyway, attached is picture of O2 sensor that located after manifold.

I have 2001 RX300 and had check engine and VSC light on before. The air fuel ratio sensors that caused this problem, one sensor is located at front of engine and other at the back, see attached pictures. Make sure that you replace with sensor from Denso, all other such Bosch is never work with Lexus. The price for these sensors is around $145.00 on line. Good luck

Thanks for some infos. If anyone have any picture or instruction of how to replace the sensor, please post. Regarding to "well-fed wife", Yes, I do need one. Is there any charge?

First, Thanks to all for some advices. I looked and checked my car headlight, they're moving up and down while parking on slope and start the key. This means the auto leveling system is seem to be working, isn't it? The light still comes on in dash board and goes off after driving awhile. Any advice is alway appreciated.

Thanks for the link. I'll look to see there is anything that may cause this.

The symbol light is intermittently come on in dash board. It said the auto leveling system malfunction in manual. Is there anyone has same or how to fix this problem? Thanks in advance.

Very appreciate for 2001 RX300 repair manual.

I had same problem just 3 week ago on my 2001 RX300 at 98K mile. I bought OBD scan code, $89.00 at Amazon.com with free shipping now, and scan the trouble code. I don't remember the code, however, it shows me that I have air fuel ratio A/F sensor malfunction. Ordered one from Rockauto.com, $157.00 then got local garage to replace for $40. Total cost was around $200.00. This is better than the quote from Lexus dealer $650.00. Make sure you order sensor from Denso which is Toyota / Lexus OEM, from Bosh or other will not work properly. There are 3 sensors in RX300, 2 A/F sensor one is in front of engine and one is in back fire wall, and one O2 sensor located after manifolded. These A/F sensors are last about 100K mile. I have some pictures or if you need more help, email me at simba2k@yahoo.com. Good luck.

The VSC light on on my 2001 RX300 63K mile. Does anyone know why and how to fix it? Thanks in advance.
