I believe some claim the new Crown sensors work in the cold but I can't vouch for those claims. I just know when I replaced my OPDA ('05 4.0), it was fine until it got cold and started throwing codes. My original sensor broke when I tried to remove it from the original corroded OPDA. I bought a Mopar sensor (actually 2 if I recall) that threw codes when cold.
Then I bought a used OPDA on eBay with an original sensor. I installed that sensor and no codes through 2 winters so far.
Good luck.
