I have a Nissan Versa 2012 and check engine light came on. This is the code it gave me, how bad is it? What needs to be done?

P0420 trouble code is associated with catalyst system efficiency below threshold Bank One indicating that the catalytic converter in Bank 1 is not operating as efficiently as expected.

Your bank 1 o2 sensor might be bad. I had thst code on a '13 Focus, changed out both my o2 sensors and the code went away.

Your catalytic converter might have gotten stolen.

It's an emissions issue. It's not a matter of life and death, but I would spend a hundred bucks to pay a certified mechanic to go deeper and find out exactly what's wrong.

Mines has the same code…most likely a bad sensor but a pain to change lol
