I just got my car back from a local mechanic. They said it was a bit difficult to locate, but they were able to find a problem in the harness. The sensors were fine, but the bad voltage due was triggering the codes for the 02 and Knock Sensor.

Basically mikebontoft hit the nail right on the head.

Thanks for the replies, everybody! Hopefully I can drive cycle a few days and get through inspection soon before any more issues arise! hehe
