[JoshGX460werth]

Anybody have an advice on diagnosing the root cause of the P0430 code? For instance whether it’s the ox sensor or the catalytic converter.

Trouble code P0430 (catalytic converter bank 2 below threshold). - ClubLexus - Lexus Forum Discussion

GX - 1st Gen (2003-2009) - Trouble code P0430 (catalytic converter bank 2 below threshold). - OK...06' GX470 CEL light and the others came on the other day when we got the cold snap. Gas cap is new so any chance for the quick fix is gone. Took it in and it threw that code...I've researched here...
