"This code is output when the AYC-ECU power supply voltage drops below, goes
beyond, a specified level.
-Defective harness or connector

Almost certainly related to your turbos. Possibly the alternator though?

Out of curiosity does anyone know what either of these mean?

Think it was either 41 or 46 anyway...

41/42 TPS system (open- or short-circuit)
45/46/47 Pressure sensor system

System had a full flush and was bringing up these numbers...
