Hello, the P0420 code is not related to an evaporative emissions system leak. It is a catalyst inefficiency code.

You'll need a diagnostic tool to monitor the oxygen sensors -- before and after the catalytic converter -- on bank one, which is the affected bank. You likely will need replacement of the affected catalytic converter.
