The code means the converter on the side cyliner # 2 is not working like it should ,to check to be sure you need a scan tool and data from the front and rear o2 sesor cannot mimic each other if they do the converter is bad ,there are aftermarket converters for that car but they dont preform as well as the factoy one .

Definition of Diagnostic Trouble Code P0420 Category: Powertrain Definition: Catalyst System Efficiency Below Threshold Bank 1Note: This definition of P0420 is applied to all manufacturers

Definition of Diagnostic Trouble Code P0430 Category: Powertrain Definition: Catalyst System Efficiency Below Threshold Bank 2Note: This definition of P0430 is applied to all manufacturers

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.

P0430 Catalyst System Efficiency below Limit - Bank No 2" How would I fix that without taking it in? P0430 - Catalyst System Efficiency Below Threshold (Bank 2)
you need a scan tool to monitor the upstream and downstream 02 sensors on bank 2 more than likely its the converter. also check for exhaust leaks before converter . Most times the problem is the Downstream O2 sensor2_bing.gif is defective.

Code PO42O and PO43O ? Anyone know what they


The meaning of: P0420 Catalyst System Efficiency Below Threshold on Bank 1 P0430 Catalyst System Efficiency Below Threshold on Bank 2

Basically the Oxygen sensors ( one before and one after the catalytic converter ) have abnormal readings from the exhaust. Further diagnosing will need to be done by a mechanic to find the source of the problem. The possibilities could be the O2 sensors themselves, a leak in the exhaust manifold, a bad catalytic converter, and etc.

2002 Hyundai Sonata code reads P0430 what does this mean Catalyst System Efficiency Below Threshold (Bank 2)


That's a pretty RELIABLE code!... You have a bad CAT (Catalytic Converter). Trust it to be accurate. The conditions which set this code is when the Upstream O2 sensor's data/signal is compared to the Downstream sensor's data/signal... when they are nearly identical, that's when this code is set (unless you have an exhaust leak).. If there is an exhaust leak.. repair it, then retest/recheck.
