After getting under there, I saw that the previous owner had used the AutoZone universal O2's and the connectors look like they were from something he had lying around - they were spliced in on both sides of the connector.
So after much searching, I got the OEM connectors from a Mercedes dealership and bought OEM style AC Delco O2 sensors. I neatly spliced them back into the engine harness, using the wiring diagram/color codes from the service manual.
Now I have only the 0141 and 0161 codes - heater circuit malfunction on both rear sensors. It seems odd to me that it's both and the likelihood of getting two new sensors with bad heater elements seems slim. I've checked and have 12.9-13V to the O2 sensor plugs, but haven't tested them under load because I don't have the tools to do so where I am now.
Is there anything else I should be looking for or common problems with this?
Clearly you have the intellect and mechanical ability to maintain this vehicle, your answer is within the wiring schematic and service manual it's just going to take a little thought and a little digging to find it. I personally stay as far away from the Chrysler dealer as possible. This forum and the crossfire owners on it through their experience have saved me more money then I can shake a stick at, the last time I relied on the dealer for anything was to have the convertible top replaced under warranty. You do as you please but I personally from experience trust the members of this forum.
