One of the wires attached to the AC sensor located near the high end line was damaged by rodents. The damage is very close to the green rubber connector so not feasible to solder the damaged wire as a fix. Not sure if or what my other DIY repair options are. Any thoughts or suggestions.
After further research it appears that the damaged wire it attached to a pressure switch and not a pressure sensor. Either way, I still need to figure out how to best deal withy the damaged wiring.
You'll have to take the connector off, and apart to solder another wire to connector, and to the original wire. Use weather proof heat shrink tubing.
You're driving a Gen 3, so yes, that is a pressure sensor, not a switch (it was a switch in Gen 1 and Gen 2). The endorsed way to fix that is to look up the part number for the Repair Wire, as you see in this example here (this is just an example, this picture is for a different connector!). This post and this one show you how to navigate through the online wiring diagram to that information. Another easy option, when you're just looking up one repair wire like this, is walk up to your local dealer's parts window, explain which connector you're dealing with, and let them look up the repair wire. As you see from the picture, there will be the part number for a "repair wire" (which is a length of wire already pre-crimped to the correct connector terminal), and also for the correct crimp sleeve to use (at the free end of the wire, to splice it to your existing wiring). Bring those home from the dealer parts window and you're ready to go. The picture will also show exactly how you release the old terminal from the connector housing. The repair wire is long enough that you can cut your old wire some distance back from the damaged point and make the splice there, to get back to good copper. You can choose that point anywhere within the length of the repair wire (you can trim it too, don't have to use the whole length). The crimp sleeve, since it's an underhood application, will be a weatherproof kind that will shrink around the splice when you heat it, and ooze out a sealant.
