2013 Chevrolet Volt Premium
Hello, today I went out for a drive, parked my car, and when I came back I was met with the lovely "Service High Voltage Charging System" message, which I have never received before. My OBD scanner pulled 3 codes: P1e00, P0aa6, P1fff. All coolant levels appeared to be good and it drives well on the gasoline engine. I have a hunch it's a coolant sensor but any other ideas would be nice.
