Question Air fuel ratio sensor. Please thanks
 

Question regarding the air fuel sensor or otherwise known as the oxygen sensor, i got this service engine soon icon popped in my gauge, it wasn't blinking or anything, but it was on. So I've checkec it with a scanner and it says that it was because of the "air fuel sensor" googled the image for where I can find it, and found tries to remove the sensor it was located near the catalytic converter. I tried to delete the error for now, and will be observing and posting the pictures of the actual sensor soon. I drove the car for a day now and no signs of that service engine soon icon on my gauge. Thank you
