Oh OK thanks bro, the fault code reads bank 1 sensor 1 which is directly behind the radiator and attached close to the exust manifold

I scanned my car few months ago and it gave that error of air and fuel ratio sensor malfunctioning, and I have replaced the O2 sensor and it keeps repeating the same code at different times. Pls can someone pls tell what I can do. I also noticed that it consumes more gas lately.
