P0430 code possible cheap fix
2005 Frontier CC 4x4 4.0 v6
had ses code P0430 (catalyst bank 2). Cleared codes, disconnected battery, nothing worked, ses kept coming back on. Was getting rready to replace O2 sensors (bank 2). Then the ratchet mechinism on gas cap broke. Prior to that, cap appeared to seal OK. Replaced with new gas cap. ses light went out after about 75 miles and hasn't come back on.
go figure.
