What does that mean?
"loose wire at the computer"?

The DME connector is one single plug that has 88 pins. Those go to wires in the harness that have electrical connectors on them. It's highly unlikely there is a "loose wire at the computer." It is entirely possible there is a loose wire in the O2 sensor plug or that the wire to the O2 sensor got yanked/crushed/melted at some point.

P1117 is for bank 1 after the cat, i.e. passenger side rear. Check the electrical plug for that. Make sure it's seated properly. Make sure the pins are all intact. Follow the wires to the O2 sensor and look for anomalies.

If you don't see anything you can try swapping the sensors to see if the problem is the sensor.

Edit: Just looked at the diagram and the O2 sensors go through the X59 plug (white plug to the left of the DME).

Wiring for Bank 1 O2 sensors are are:
DME pin 77 → X59 plug pin 17 → O2 plug pin 4
DME pin 1 → X59 plug pin 15 → O2 plug pin 2

P1117 is for bank 2 1 after the cat, i.e. driver's passenger side rear. Check the electrical plug for that. Make sure it's seated properly. Make sure the pins are all intact. Follow the wires to the O2 sensor and look for anomalies.
