2011 Pathfinder with an OBD2 code P2a00

[dtvau]

Hi,
I'm a newbie to this forum :-)
I have 2011 TI550 Pathfinder and it is showing an engine fault code P2a00.
I've found the following post http://engine-codes.com/p2a00_2011_niss ... inder.html but interested to see if any other 2011 owners have seen this issue and have a reliable fix. From the post it sounds like either a sensor issue or potentially an exhaust leak. Any help would be greatly appreciated and any advise on where I get the part number and buy one.

Thanks in advance
David

Welcome to Nico!

I don't have experience with that one, particularly, but I did a search here and turned up a bunch of O2 sensor discussions. That makes me think you're on the right track. Hit search in the top right and enter "P2A00" as your search criteria. That'll search all of the forums on nicoclub, not just the Pathfinder/QX4 forum.
