2G Coolant temperature sensor wiring diagnosis

[oh-b-1g]

Exact issue first. Then what I did immediately before the issue.

Coolant sensor circuit malfunction code on v3 lite is, of course, making the car run very rich. Just about won't start. When I measure the voltage of the white striped feed wire, it reads 4.7-4.9. When I read the solid black wire I get 6v instead of ground.

I recently cleaned up some wiring in my car and broke the wires off of the 2wire coolant temperature sensor plug. I depinned the connector and removed the remaining wire and crimped in new ones. Then I put spades on the other ends and installed the patch harness Next, like a true dummy, after a quick check of the internet, and not immediately finding it in my FSM, I just guessed and tried it. No bueno. Then tried the other way. Same. One or both of the leads may have touched the positive battery terminal while I was working. It was 5am after starting work on the project at 10am the previous day, so I was probably too tired to be doing any wiring. Hoping I didn't fry the coolant circuit.

Link reads -74° no matter what I do unless I lock the voltage check box which yields no numerical value on a log. When I do lock that voltage, I get intake air temp, and parometric pressure codes.
