Heard a ticking coming from the center top part of my engine. Drove to work the next morning and the check engine light came on. Scanned it and got a P0324 knock sensor performance module DTC. Put a new knock sensor on it and the issue went away. On the drive home from work last night the ticking returned. The check engine light hasn't come back on yet but I'm almost certain it'll come on when I drive to work today. Anyone else have this issue or any experts have an idea of what the issue might be?
Anybody mess with the spark plugs in the last year or so?......this engine will loosen them (and tick) if they weren't properly tightened.

My first thought from this distance,
