Rodents chewed wiring but car runs, should I repair?

Rodents chewed through the wiring of my vehicle listed above Touring, with 166,000 miles. The car lives on the street, so it's not in great shape. It has hail damage, scuffs from people bumping it when parking, damage on the ignition cover and a new side window from a theft attempt.

**The car runs fine**, but the check engine light is on. The check engine light used to come on and off with a fuel leak code, but I think since the wiring got chewed up, the check engine light has been constantly on. Have not checked what code it gives now.

Given the state of the car, I don't think I could get more than $1,000 for it, so I'm wondering if it's worth repairing.

Can the severed wires be patched, or would the entire engine wiring harness need to be replaced? I figured replacing the whole wiring harness would cost north of $1,500, more than what the car is worth.

The dealer said they think the severed wire was connecting to the camshaft sensor, but I'm not sure.

Is it worth repairing? How costly do you think it may be?
