Just had the P0430 code pulled on my 2006 with 82k miles.
Planning on doing the following
1) check gas cap and try a bottle of injector cleaner (can't hurt)
2) look at cats for obvious "issues"
3) assuming cats look good replace O2 sensor(s)
Only question is can I check O2 sensors to determine they're bad?
Already pulled the fuse to reset the code so i may do step one and if it stays off I'll consider myself done till next time.
Thoughts?
