What does diagnostic code P0430 mean?
catalytic converter
Code P0430 indicates that the catalytic converter is not functioning efficiently, therefore increasing the output of harmful pollutants by the vehicle.
What does p0430 mean on Honda catalyst system?
P0430 HONDA Tech Notes 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).
What does DTC for p0430 stand for?
P0430 is a diagnostic trouble code (DTC) for “Catalyst System Efficiency Below Threshold (Bank 2).” It warns about a problem with the catalytic converter mounted near engine bank 2 (the side of the engine opposite the number one cylinder).
Which is the mirror image of the p0430 code?
The P0430 code’s mirror image is P0420, which applies to the converter on bank 1. As was mentioned, bank 1 and bank 2 simply refer to the different sides of the engine.
What causes a P030 code on a catalytic converter?
That’s how important the converter is. An upstream leak in the exhaust system, such as a crack in the exhaust manifold or a loose header pipe at the manifold that allows air to enter and confuse the upstream sensor. One possible cause of the P030 code is a damaged or failing oxygen sensor.
What to do if your Honda has a p0430 code?
If the P0430 code is combined with other codes, try fixing the other codes first. The Powertrain Control Module (PCM) software may misinterpret sensor inputs as a deteriorated catalytic converter. Update PCM program to resolve the problem. The cost of diagnosing the P0430 HONDA code is 1.0 hour of labor.

Why is the p0430 catalytic converter not working?
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. The Powertrain Control Module (PCM) software may misinterpret sensor inputs as a deteriorated catalytic converter.
