WOW! I have been throwing the same code for over a year now and I'm still trying to figure it out. I had a buddy check up on that code and apparently in some cases a small exhaust leak can cause it.

I'll be tightening down my exhaust here this week and clearing the code to see if it helps.

But yeah, I went to bring my car to the dealer thinking it was just a bad o2 sensor but the tech blamed it on my HFC because of the anti fouler bung....
He said the rear sensors were throwing off the front. Uhhhh, I don't think so Mr.'Certified' Nissan Tech or their 'top' tech as they called him. I was lucky enough to have a nice service guy because he waived my $85 inspection fee because he knew it was a bulls*** diagnosis.

I was actually going to post up on here soon if tightening the exhaust didn't work to see if anyone knew the problem.

Mine aren't bad, but I throw a code (same one every time) every so often. When I first threw it I took it in and they refused service, because they said I lengthened the O2 sensor wire...

Why would I lengthen it? If it was any longer it'd be hanging down and potentially get caught on something I drive over, or rub on the road.
