Bank 2 catalyst efficiency below threshold. You are dead on if the downstream switch as much as the the upstream then it has failed and will need to be replaced.
On another note, aftermarket cats are much cheaper but also much worse at their job.

2006 Mitsubishi Lancer. Im only keeping it for about 6-7 months, so just need one good enough to pass inspection, not one that will last long term.
