What to do if your Kia has a P0420 code?
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 P0420 code is combined with other codes, try fixing the other codes first. What does this mean? Cost of diagnosing the P0420 KIA code Labor: 1.0
Can a P0420 catalytic converter be replaced?

What does the P0420 code on Honda Accord mean?
Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. As the code description implies the P0420 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 code P0420 mean on PCM?
Code P0420 represents a problem. However, if the downstream O2 sensor starts sweeping between rich and lean, or constantly reads a rich or lean condition, that’s an indication to the PCM that the cat converter isn’t doing its job of cleaning up the PCM’s mistakes.

Where is the P0420 OBD2 trouble code stored?
The front O2 sensor measures the mixture, and it tells the engine control unit if the engine is running with a rich or lean mixture and adjusts it. The rear O2 sensor is just a diagnostic O2 sensor for this trouble code. If the rear O2 sensor is getting faulty values, the p0420 code will get stored in the engine control unit.
