You can't really tell anything from digital data from an 02 sensor, you need analog data as shown in this video:https://www.youtube.com/watch?v=UNzi30G2_Kk $15 elm327 bluetooth module and the free torque app or similar that will chart analog data. You should see the 02s cycling regularly.
This is the best coil/wiring diagram in imho
Well, It is my current understanding that the o2 sensors for example, will sit at certain voltage values if good, and another value if bad. What I find interesting, is the huge disparity between the two voltage values of the front sensors.

Absolutely incorrect, you need to watch the video.
-40 deg F is the minimum value of the sensor range. It probably means the sensor is disconnected, or otherwise open circuited (e.g. wire is broken or cut or disconnected). I would get that temperature value (on the Torque app) when one of the wiring splices on the ground wiring became loose. Took a good bit of detective work with the wiring diagrams to track it down.
