I am looking to replace the Air fuel sensor on 2008 es 350 Lexus and I was wondering which is considered left and right. I am looking to replace the sensor closest to the radiator which is bank 2 is this considered the left side.

 

Here's a good schematic drawing: http://www.justanswer.com/toyota/57o...2197-code.html Did you attempt to contact Lexus?

 

Not yet I am going to try changing out the sensor first since it is easy enough. I will be calling after this is done. Thanks allot for the info this has helped.
