computer scan shows PERMANENT code

Recommended Posts

My 2014 Silverado is showing a P0430 (1/1) Permanent code.  Catalyst System Low Efficiency Bank 2.

I was trying to clear the code after replacing the Catalytic Convertor and it went to " Permanent" in the computer. Is there a way to clear this or will I have to let Dealer clear it?

Google " Universal Trip Drive Pattern ". That might help. Apparently No one can clear permanent codes with a scanner. News to me. Never seen one.
