Code P0420 means "Catalyst System Efficency Below Threshold (Bank 1)" P0420 is actually Catalyst System Efficiency Below ThresholdCatalyst System Efficiency Below Threshold. Bank 1 is the side of the engine with cylinder #1. This code means that the catalytic converter is not cleaning the exhaust properly or the oxygen sensors are sending false info to the computer.

Yes, DTC P0420 refers to a catalytic converter that is not work properly. It doesn't hurt the engine/safe to drive, but will fail for above exhaust emission.

I have a 2005 Impala as well.....I bought a code scanner when my check engine light came on....2 codes came up on the scanner...P0420 and P0420PD.....'catalyst below efficiency'....My car has 115,000 miles on it and it was time for annual safety/emissions inspection so I took it in to a shop.....The catalytic converter had gone bad and had to be replaced.....which was the reason for the P0420 code....
