Kia Sportage: Knock Sensor (KS): Description and Operation

Third generation SL (2010–2016) / Kia Sportage SL Service & Repair Manual / Engine Control / Fuel System / Engine Control System / Knock Sensor (KS): Description and Operation

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. When a knock occurs, the sensor produces voltage signal. The ECM retards the ignition timing when knocking occurs. If the knocking disappears after retarding the ignition timing, the ECM will advance the ignition timing. This sequential control can improve engine power, torque and fuel economy.
