Ign NGK/NTK Knock Sensor ID0002 (72931)
The knock sensor ignition determines if engine knock is present (caused by detonation).
A varying voltage is generated by a piezoelectric crystal based upon engine vibration intensity, which sends a signal to the ECM.
The signal is used to retard ignition timing, preventing engine damage caused by pre-ignition.
Located on the engine block, common causes for replacement include illumination of the check engine lamp, engine hesitation, poor fuel economy, and failed emissions tests.
