it usually means there is a temporary problem that has corrected itself. might wanna check for codes to be on the safe side...

Pull the codes to find out what sensor(s) triggered it.

Check here to learn how without a scanner.

It could have been as simple as having bad gas, causing it to ping just enough for the knock sensor to pick up. Really, it could have been anything. Pull the codes first.
