Did you change the trans or the ECU at all at some point recently?

It shouldn't be throwing those codes if you didn't change anything but the motor. With a 5spd it should be throwing codes for the auto tranny. Im not sure if the auto ecus and 5spd are the same or not.

The only thing the ECU sees from the 5psd trans is the speedo. And if the ECU doesn't see speed, it won't throw a CEL. Plus, the 5spd doesn't have any sort of neutral switch.
Out of curiosity, in the engine bay by the ECU, do you have another unit next to it that looks like another ECU? Should be on the same braket
