Have you actually looked at scan data to see what the o2 sensor is doing? If the front sensor is not indicating a lean condition, the rear one on the same bank should not indicate a prolonged lean condition either. If you have replaced all you have said, make sure there is no exhaust leak before the sensor. It is possible to have a defective sensor right out of the package and this is why I suggest to look at scan data to make sure the sensor is correct on what it tells the computer.
Scan data showed bank 2 sensor 1 running 44%. I replaced both the upstream sensors again and code has returned. Also found that the clutch for the fan had gone out. Fixed that too. Money Pit! I was thinking of trading it in and getting a new truck but I'm not really ready to pull the trigger right now. Also seems like everything on the market is junk now.
MAke sure you dont use cheap sensors and they have to be NTK or NGK or you will continue to have problems. Trust me. Just went through this and changed everything possible. WAs the aftermarket sensors. USe Mopar or NGK or NTK
ALso when you have changed them, disconnect batter for several minute to clear the PCM. if you dont it will continue to use the data from the time you ran the sensors with issues and try to adjust according to that. It needs to reset and start reading new data from new sensors.

Hi John,here's a link about your P2098 code. P2098 Post Catalyst Fuel Trim System Too Lean Bank 2
SOURCE: 2004 x-type 3.0 v6 152,000 miles showed codes P0171, P0174, P2096, P2098, P0101, P0171 pd, P1000.
check for vacuum leaks or a faulty mass air flow sensor. all the codes have to do with engine too lean(too much air).

Hi!!
The O2 sensor for Bank 1 is located below left front of transmission, in exhaust. Check diag. below.
