2009 aveo 420 code

[tacomafitch]

My 2009 with 182K miles came up with a 420 code earlier this week but i reset with the scan guage now twice today. Hopefully not the cat. Any words of encouragement ?

Gloom and Doom: P0420 Error Code: Catalyst System Efficiency Below Threshold (Bank 1)

Just kidding just make sure that it does not come back otherwise that might mean replacing the Cat converter.
