O2 sensor help ASAP

[symon_say]

Hi

I need to change one of my O2 sensors, i get the code P1151 for sensor 2-1, the mechanic check it and told me it was bad, what sensor is this the one that goes after or before the cat and are there any difference betweens sensors for bank 1 and bank 2, or are they just before and after.

Thanks.

I found this one, but i dont know if this is what i need.

PD: Sorry for this, english is not my native language and is a little hard to find things sometime.

Bank 1 is right side-bank 2 left side
sensor 1 is upstream of sensor 2.

there are 4 oxygen sensors-
does this help?

I guess this means that sensor 2-1 is sensor before catalitics, right??

And if so, are they the same cause i'll change both so i dont have trouble in future from the old one.

Yes-
bank 2 sensor 1 is the easy one to get to-right under the engine.

Have you tried everything else first?

Thanks a lot man.

You are very welcome-
Hey-just a thought. You might clean the MAF sensor. Remove the air filter box from it and spray MAF sensor cleaner in the fine filaments-
