Hi all I brought a Bluetooth, elm scanner and it works great in real time,
Its accurate with my temps, rev, speed and most things but it has given me one concern.

I have 2 o2 sensors 1 before and after the cat, one seems to give a constant .5v and the other fluctuates from .2v to 1v at random when running and with just ignition on it holds at .5v

Do I trust this in foo is there a way to double check this

Thanks in advance
