O2 sensor voltage and STFT
![Post Post](./styles/Cerulean/imageset/icon_post_target.gif)
I was looking at some data on a obdII scanner and something doesn't seem right. Maybe someone help me understand if the data below is normal.
My o2 sensor voltage seems low at idle. I read somewhere that said .45V is the norm.

Maybe the sensors are o2 sensor are bad and is the cause of my P0171 lean code.
And are short term fuel trims suppose to be at 0 at idle. It also never moved from while revving in neutral
