Default HELP!! System too rich

CODES
P0172 System too rich bank 1
P0175 System too rich bank 2

EDIT: Btw i'n not using an OEM bank 1 sensor 1 O2 Sensor, it may be the problem but i want to be sure before buying the DENSO.

I'll leave a freeze frame, i'm really new in this and i don't know where to look at.
