Guys need some help, CEL came up w/ P0141, bank 1 sensor 2. I think I need part 234-4626 (front lower ) from denso but is not sure. Anybody happen to know the exact part number for this on the car, start out with number 8. I got 89465-53110 from google, but toyota told me, they don't have this part in their database. I got 2001 GS300. Thx

oxygensensors.com has them.

jcat but this is what you provide us b4 in reply to swat post.

your post:
"no, you're right, that's my mistake. I'm thinking banks in terms of upstream and downstream, it's actually just as you diagrammed it, in terms of cylinder banks.

bank 1 is cyl 1-3 and bank 2 is cyl 4-6, sensor 1 is precat, sensor 2 is post cat. 234-4626 is the one you need.

my bad damn sleep deprevation "
