The Knock Sensor detects vibrations caused by engine knock or detonation and sends a signal to the vehicle’s computer. The computer checks this information against preset data to determine if the vibration was caused by an actual knock or ping. If the computer senses a knock, it will recalculate the data and retard ignition timing to eliminate pre-ignition.
