I have an 07 Jeep Rubicon 3.8 and I have replaced all 4 cats, Mopar o2 sensors, plugs and wires and MAP sensor. Still getting o2 sensor codes and engine light won't shut off. Tried my scan tool and battery disconnect and still present. Any help would be greatly appreciated.

 

Suggest having someone who can trend graph the O2 sensors take a look at it. There are many O2 sensor codes, each with different possible causes. Analyzing the O2 sensor graphs, and whatever codes are present will lead to a solution.

Stay in touch, curios what the solution turns out to be...
