Can oxygen sensor cause catalytic converter code?
Often times this code is thought to be a faulty O2 sensor or A/F Sensor; while this is a possibility, the most common problem is a faulty catalytic converter. Do not overlook other codes that are paired along with P0420.
How to clear catalytic converter codes without replacing?
Disconnect your cars battery. This will reset the computer and clear the existing error codes. Locate the oxygen sensor that is downstream (closer to the tailpipe) of the catalytic converter. Remove the sensor, and take to your local car parts store.
What does check engine light mean on catalytic converter?

The sensors will trigger an Onboard Diagnostics (OBD) trouble code that’s stored in your car’s computer. OBD Code P0420 means the catalyst system efficiency is below the threshold.
Why does my catalytic converter keep coming back on?
If the light eventually comes back on, then you have a more serious problem, and you might need that expensive replacement. However, there are still other less-costly causes for a trouble code P0420. Such as: Failing oxygen sensor (remember that’s always a possibility). Damaged wiring of the oxygen sensor connections.
How can I fix the P0420 code on my catalytic converter?
To fix the P0420 code, you need to diagnose what is causing the trouble code. Start with inspecting and diagnosing your catalytic converter and continue with checking the O2 sensors. What can cause a P0420 code? A bad catalytic converter is the most common cause of the p0420 code.
Does a catalytic converter damage the engine?
A bad catalytic converter will not cause major damage to your engine. The most common impacts are reduced performance and bad fuel efficiency. When it comes to physically damaging your engine, a bad catalytic convert can only cause wear and tear damages.
What happens when a catalytic converter fails?
