Hi everyone. My 2011 R/T is getting a Check Engine Light with code P0153 O2 sensor slow to respond. The light has come on twice since I picked up the car last week. 1 O2 sensor had already been replaced. Any thoughts? Thanks.

If the Bank 2 oxygen sensor upstream of the catalytic converter has been replaced by the dealer and your PCM is still throwing a code, you should check the following:

1. Wiring problems (shorted, frayed wires)
2. Inlet air leaks or exhaust leaks.

Thanks for the info. I now know what questions to ask when I pick it up.

Just got the call from the dealer. They found the Bank 2 oxygen sensor not fully seated and cross theaded. New parts ordered. Looks like it. Thanks for your input.
