Sensor 2 is always downstream, or after the cat. To determine bank 1/2, use a scan tool and view the data for o2's. Unplug one and see which goes flat. The scanner will show sensor name and lack of signal.
The #1 bank is the rear bank of the engne, the #2 O2 sensor will be after the catalytic converter. I hope this helps. Take care.
Sensor is behind engine and between engine and firewall, the spring on electrical cable should identify it. One recommend you go to you tube for removal and installation.

The sensor you indicate would be on the manifold of the head containing cyl.# 1, top sensor (prior to catalytic conv.) 6 cyl. engine. 4 cylinder would be sensor on exhaust manifold. Confirm sensor failure prior to replacing as chrysler harness connectors are known for pin failures at 02 sensor connections. Inspect for burnt pins and cracked/chaffed wires first before changing sensor.
it is the sensor in the exhaust manifold in bank 1 before the cat converter
