Welcome to the site. I moved this thread to the Stratus section,

Welcome to DF
It is time to pull out the DVOM and start checking the wires from the controller out to the o2 sensor connector and check power and grounds and ohm test too. You could have either an open wire or bad ECM.

 

I had the same problem on a 2006 Stratus with the 2.7 V6. After the new sensor was replaced the light came on again. The mechanic tried another sensor, same problem. It turned out to be the connector on the harness side.
