Code P0430 2006 Infiniti G35 Description

The P0430 code for a 2006 Infiniti G35 indicates that the Catalyst System Efficiency is Below Threshold in Bank 2. The catalyst system is responsible for converting harmful pollutants in the exhaust gases into less harmful emissions before they are released into the atmosphere. When the efficiency of the catalyst system falls below a certain threshold, it means that the catalytic converter is not functioning as effectively as it should be.

Tech Notes for P0430 2006 Infiniti G35

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.
