i went to kragen to buy three 02 sensors today and they couldn't figure out which ones I needed. I told them I needed
bank 1 sensor 2
bank 1 sensor 1
bank 2 sensor 1

they said they didn't know what that means.
i looked in the haynes maxima book, all i could find was

the codes I have mean
upstream 02 sensor right and left bank
downstream 02 sensor left bank

but its not described like that anywhere else when you try to buy them. anybody know the part numbers or what i should say.

 

Why 2 threads?

 

i tried to post one, then it didn't show up so i tried again. sorry.

 

NEVERMIND problem is solved. a maxima only has 3 o2 sensors. wow i'm dumb

 

my bank 1 sensor 2 went out a few months ago i was about to replace it but i decided just to clean it with a wire brush. I never really heard that cleaning an o2 sensor actually will fix it. CEL went off on it's own and hasn't come back on since. You might want to try cleaning them before you replace them.

bank 1 sensor 1 = sensor in y pipe closest to radiator
bank 1 sensor 2 = sensor in y pipe closest to firewall
bank 2 sensor 1 = sensor right after the cat

Why the Maxima needs 3 sensors we may never know

Oh and why the wiring harnesses for the 02 sensors are on top of the engine we may never know but they are sure easy to get to

PS you can always delete your other thread if you made 2 by accident
