Replaced the o2 sensor bank 1, still getting a code...

Iv been googling the subject, but id like your guys input as well.

Im trying to make a check list of stuff i should start checking to get rid of this code other than changing the sensor it self since iv already done this i think it must be something else causing it to show.

Any thoughts of what i should look at? i just recently replaced the MAF sensor as well.

 

i think i posted this is the wrong section, can someone move it?
