Catalyst question.

[Waldo]

hi.. got a cel on 2016 6cy Nox.. code comes up P0430 and translates to Catalyst system efficiency below threshold, bank 2. And some more digging on OBD comes up with Catalyst monitor bank 2. so i am not sure if this is a sensor or catalyst issue...
any ideas or help be appreciated.
thanks A

Chances are it’s the converter but that seems a bit short on the CAT life if it’s a stock 2016. This presumes you have not had any abnormal consumption of oil into the combustion chamber, or continued use of the vehicle with an uncorrected misfire condition.
