Need some info - O2 Sensor Location
 

My '97 Millenia just set a P0147 CEL code. The autozone guy told me this was a bad O2 sensor - bank 1 sensor 3. I'm pretty sure bank 1 is the side closets to the firewall but I don't know which sensor is sensor 3. Can someone point me in the right direction?

Am I correct bank 1 is the side closets to the firewall?

Thanks in advance for any help.
