Neatral safety switch error code on a 1999 nissan frontier?

SOURCE: Knock Sensor 2002 Nissan Frontier

The job of the knock sensor is to detect the vibrations of engine "knock" caused by an advanced ignition system. It allows the fuel mixture to run extremely lean and efficient and when it can't perform at maximum effeciency, it "knocks" like it has bad gas and the computer gets the signal from the sensor and changes the ignition to ****** the spark and make the knock go away. If the computer is confused by the signal (too much signal, no signal or too frequent signal) the computer flips the light on with a 0402 code.

If you hit a pothole and the light goes on it might have got too much signal. If it starts going on at other times, you may have a sensor that is sending out too many signals and it might be from bad gas that the computer can't control the knocks.
