What does this mean?

Tech Notes for P0430 2006 Ford Fusion

As the code description implies the P0430 code means that the vehicle's control module has detected that the three-way catalytic converter is not working properly (is not as efficient as the factory is expecting). Replacing the oxygen (O2) sensors may sometimes fix the code, but in most cases the catalytic convert needs to be replaced to fix the problem. If the P0430 code is combined with other codes, try fixing the other codes first.

When is the Code Detected?

- Three way catalytic converter Bank 2 does not operate properly.
- Three way catalyst converter Bank 2 does not have enough oxygen storage capacity.
