Is it possible that bad ECU may cause P0330 & P0325, have changed both knock sensors and its wiring harness, still shows these codes

My 2008 Saturn Outlook just gave me a code of p0330 it tells me to put premium gasoline for at least two months or should I just replace the knock sensor?
-
Due to the age of your vehicle, you probably have to replace the knock sensor, but it's worth trying using high octane gas, at least for a month. High octane gas will also help clean some of the engine carbon deposits. If possible add a fuel additive.

Thank you, i will do the premium for a month and see if the code goes away because as of right now my engine light has not come on, but if the part is not that expensive i might as well get the part and replace it and start using premium gasoline from now on. Thank you for your responding that fast.
