Order of inspection
P0328 Knock Sensor 1 Circuit High (Bank 1 or Single Sensor) Medium
The P0328 code means the knock sensor signal is above the expected maximum. It can be an electrical fault or real mechanical noise that the sensor is picking up and that is not knock. Telling the two apart keeps you from replacing a sensor that works correctly.
