Default Upstream A/F sensor bank2 sensor1

I got code p2241 and p0051 both stating low positive current control circuit and low heater control circuit in bank 2 sensor 1. I have all the tools ready but I am not able to find the appropriate A/F sensor online. I'm not sure how to tell if a sensor is heated and if I need a heated one. If anyone could direct me to where i could find a specific one for my case or post a url that would be very helpful! Thanks!

Edit: I have a 2003 V6 Camry
