driving to a NYS inspection station my CEL light comes on, PO161 bank 2 sensor 2... any idea where this plug is and what plug I would purchase to replace it. I'm guessing sensor 2 means post cat but can someone confirm. I'm going to order from rockauto.com but I'm not sure which model would be the right one. Any help would be greatly appreciated. Thanks.

I guess you didn't use the search. I believe that is the oxygen sensor.

I know its an oxygen sensor, I'm just trying to figure out which one. I guess I'll just order the one designated for "rear" and see how that goes... i was saying "plug" but thinking O2 sensor. I guess I'm really after the OEM part # to use as a reference.
