Default P0328 on cold start only?

So my car is beginning to report "P0328 Knock sensor circuit high input" on cold starts. In the morning when I start the car (cold start) I almost immediately get P0328. I can reset the CEL any number of times and it comes back as long as the engine is cold. Once the engine warms up, I can clear the code and it doesn't report it again until the next cold start - like when I leave work.

Is this as simple as the knock sensor going bad again - its been 70k since I replaced it.

FYI - 02 OBS Wagon with 160k miles.
