Martin,
I have the same code...only and always happens when it gets rainy or wet. From what I can tell, this is the right rear downstream O2 sensor. (The one after the CAT). Hope this helps.

Hey HEMIYELLOW,
Just how many O2 sensors are there? And just what do you call the right side? Is that the 2-4-6-8 cylinder side? Tnx

i had this code too a while ago. turns out it wasa loose harness, so check your harness before you go replacing your sensor.

I stand corrected and a little embarassed.
Just checked the manual and bank 1 is the driver side.
The 04 hemi has 2 cats, therefore 4 sensors.
When I last looked this up it was for my 98 dak with only 1 cat.
