About once a month or so I get a strange fault code coming up on my Z...

I reset it and it goes away for a while.. Can't seem to find it listed.

ANY help would be GREATLY appreciated...

 

TXroadster - You don't give the year of your car, but I suspect your fault code is really P2A00, A/F Sensor 1, Bank 1. Some scan tools read the hex code "A" as "10" and display DTCs with an extra digit. From your screen shot you appear to be using the most current Nissan Data Scan app. You might want to contact them and ask about this problem.
