There should be a "b1" before each of those codes.
Is one of those a code for the electromagnetic clutch? It sounds like yours has failed due to the belt slipping. This warms a heat-sensitive fuse in the clutch, disabling it permanently. The only fix is a new clutch coil. It is assumed that this is due to compressor damange; the FSM says to replace the compressor, and that's probably what you need.
You can clear these codes from the pushbutton unit. No scanner is necessary if you have this in your car.
ECT sensor is engine coolant temperature. There may be a problem or may not. Can you read the engine temperature from the unit? Ignore the sun sensor code. They all do this, and it isn't important.
