O2 sensor location

[uditha]

Hi im getting a engine light and when checked it the cide was P2270 o2 sensor signal stuck lean Bank 1 sensor 2.

I tried to see which side is bank 1 and sensor 2 but could not get information. Can some tell me which side. I know there is 2 sensors on each side and one after the CAT.
If can let me know.

They number 'em like this: 1-1; 1-2; 2-1; and 2-2. First number is the cylinder bank: 1 is Right Bank, 2 is Left Bank. Second number is O2 Sensor Position: 1 is Upstream of cat converter, 2 is downstream of cat converter.

Thus: 1-2 means Bank 1 (Right Bank) Sensor Position 2 (downstream of cat). imp
