P0420 - Catalyst System Efficiency Below Threshold (Bank 1)

Recommended Posts

Hi Guys,

The following error comes in my Toyota corolla 2006. I have attached live data of O2 sensors and others.  What could be the issue here? Do you think there may be a faulty oxygen sensor? Or the catalytic converter should be replaced? Or any other reason?

Appreciate it a lot if you could help me at this time cause the check engine light is still on. 😟
