Need help with CEL Bank 1 sensor 1
 

Hey every one my 97 SC400 gave me the Bank 1 sensor 1 code today. I got the o2 Sensor but I dont know which one is it or where is it located. I would appreciate any help possible.

Thanks

Can any one help Please......

Come on Guys I know some one out there know about this... Any help would be appreciated

I had an idea, but couldn't verify it until I found this PDF: Lexus TSIB Engine Bank and O2 Sensor Identification.
Bank 1 Sensor 1 is almost always the first sensor (before the catalytic converter) on the side of cylinder 1 (1st in firing order). So in the case of SC400's it would be the incredibly difficult to reach sensor on the drivers side exhaust header.
