Means that the knock sensor has a high output problem,would start with a new one.They run between $50.00 and $100.00 .Fairly easy to install.
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
