Hyundai Tucson: Knock Sensor (KS)
Description
Knocking is a phenomenon characterized by undesirable vibration and noise and can cause engine damage.
Knock Sensor (KS) is installed on the cylinder block and senses engine knocking. When knocking occurs, the vibration from the cylinder block is applied as pressure to the piezoelectric element. At this time, this sensor transfers the voltage signal higher than the specified value to the ECM and the ECM retards the ignition timing.
