Hi, I have a Peugeot 208 and recently the engine light came on. When running a diagnostic, I got the fault code P0420. Could someone help me understand what this code means and how can I fix it? Thank you.

The P0420 code indicates that the catalytic converter is not functioning as efficiently as it should. Start by checking for any exhaust leaks before the catalytic converter, as this can affect its performance. If there are no leaks, inspect the oxygen sensors, as a faulty sensor can also trigger this code. Let me know how it goes or if you have any further questions!
