it's probably just registering interference noise from the electrical system, you have to set the base knock levels for each car(it's in the destruction manual).

Knock is basically detonation in the engine. It happens when the engine is really too lean. Instead of combustion which is the burning of the air/fuel u have a explosion, which can damage engine components.

if you didn't wire it up, yes it is a false reading.
