Welcome to 2carpros.
The code could mean a bad knock sensor and/or other components/faults that can trigger it.
It can vary from between $100 to $400. Vibrations do not cause the knock sensor or code to come on. A misfiring or bad knock sensor would.
For the knock sensor malfunction, the MIL will not illuminate nor will the PCM store freeze frame data.
