P0420 Message: do I need to clean the catalytic converter?
Check engine light on
I have a Nissan Note and the check engine light is on. I received a P0420 message. Is it advisable to try to clean the catalytic converter first before I take further steps?

It's worth trying to clean the catalytic converter as a first step, as it might resolve the issue if it's just a minor clog. Use a catalytic converter cleaner and follow the instructions carefully. If the light remains on, further inspection might be needed. Let me know how it goes or if you have any other questions!
