Should be the rearmost O2 sensor in bank 2. Use a wrench or O2 sensor socket to get it out. Unplug it first from the harness so it doesn't get all twisted and damage the plug on the car's harness.
An O2 sensor is used to check the level oxygen in your blood. On a car it measures the oxygen content of the exhaust to the adjust air/fuel ratio
