NTK Ignition Knock (Detonation) Sensor
The Ignition Knock (Detonation) Sensor monitors vibrations caused by engine knock or detonation to alter the ignition timing and prevent detonation. A piezoelectric crystal generates a varying voltage based upon engine vibration intensity to delay ignition timing to help prevent severe and costly engine damage. Reasons for replacement include check engine light illumination, engine hesitation, poor fuel economy or failed emissions test.
