Clio 172 ph2 057 Ecu code help!

[Pusiak]

Hi guys! My name is Tymon i'm from Poland and i have an issue with my 2002 172 sport.
I have check engine light, we read codes and there was ecu code 057 front oxygen sensor.
Oxygen sensor has been changed to the brand new Bosch, fault memory has been erased.
And i still have check engine light on and 057 code

What should i do now, please help.

Look at the live data for the front o2 sensor, it should look like this, I suspect it does not.

Check electrical continuity of all wires from o2 sensor to ecu connector.
