A P0420 code is "Catalyst System Efficiency Below Threshold (bank 1).
This would indicate that the cat is not getting quite hot enough, or is simply worn out, and is no longer performing its job.
Bank one is considered the side of the engine with the #1 spark plug, which is the cylinder farthest forward.
