Electric diagram to bypass o2 sensor P0420

[An92]

have a European Toyota yaris 2 from 2007, with a 1.0 1krfe engine with p0420 error.. I purchased an extension to remove the oxygen probe downstream of the catalytic converter, but the error appears again... Currently the probe values are between 0.1 and 0.85volts... I think that sometimes it exceeds this and the error appears.. I would like to modify the electrical wiring of the probe with the electrical filter, so as to always have volts values in the suitable range but I found various information on the net. Do you have the wiring diagram compatible with Toyota Yaris? Thank you

I apologize if I post another site, thanking you but I found this one which can be useful, however they are two different circuits
