2007 Prius Displaying P0A93 P0016 C1300 C1242 C1241

I'm the original owner of a 2007 Prius with ~115k miles on it. It's never given me any mechanical issues before tonight. I was driving to dinner when the red !, yellow !, check engine, and VSC lights all came on at once. A red ! icon also displayed at the top of my touchscreen. A moment later the parking brake and ABS lights also came on, and it started emitting a constant tone. I pulled over to the shoulder and turned it off for a moment, then turned it back on and the brake lights were off.

I drove it the final mile to my friend's house, where I let it sit for several hours before checking on it again. Only the red ! and check engine lights were now on, so I drove it to the nearest auto parts store to pull the engine codes. They are:

• P0A93 Inverter A Cooling System Performance
• P0016 Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor A
• C1300 Malfunction In Engine Control Unit
• C1242 Open Circuit In IG2 Circuit
• C1241 Low Battery Positive Voltage Or Abnormally High Battery Positive Voltage

I plan to take the car into the dealership to have it checked out by the experts, but I'm hoping to get an idea of what I might be in for so I can mentally prepare for what to expect (and weigh whether or not it's worth any drastic efforts to save a car only worth ~$2k KBB).

Thanks for any insight you can offer, fine community!
