Yes they are stored in the memory of ECU unless the are erased by a code reader.
P0328 on an OBD11 equipped automobile (everything since 1996) is a knock sensor code. I believe that it says the reading is over the high limit. You should focus on the knock sensor and the wiring leading to it. --Ken

Try cleaning the MAF with a can of elecrical cleaner. then clear the code with a OBD11 tester.
