Is Bank 2 on the right or left side?

2001NBMZ28

What's the code? Bank 1 is drivers side, Bank 2 is passenger side.

UPDATE......Thanks for the info. I have been driving 120 mi per day lately. At first i cleared the code with my code reader. The last time i let it stand and after a fill up at a different station it cleared. One of the troubleshhooting guides i used mentioned bad fuel. That must have been it. I have driven 200 mi since i filled up. I am ready for another fill up.
Attention Las Vegas....BEWARE.........I filled up at Chevron @ Warm Springs and Jones. I usually always use Chevron as Exxon/Mobile fuel is not available in LV. I filled up at a different Chevron.
