I'm dealing with the same code popping up on my supercharged 2014. I've cleared the code and run the PCM tests in Forscan as well, but the tests didn't show anything and the code continues to come back. I also took it to my local Ford dealer, but they didn't want to touch the truck because it's supercharged, has a JDM tune, blah blah blah. Since the nearest Roush certified Ford dealer is about an hour away, I reached out to JDM to get their thoughts. Below is the response that I got from JimIII.... figured it might help you or someone else dealing with this code. I'm still in the midst of trying to resolve this, but I must say that I'm super impressed with JDM being willing to help troubleshoot.
"Sounds like a faulty knock sensor or the harness might be shorted. Another possibility is a shorted connection at the PCM...
I would pull the tune out for a little and see if the code goes away. but it's likely an issue with the sensor too.
We can look over the tune but let's resolve this first because the knock sensors can affect engine performance."
