Hyundai Azera: Knock Sensor (KS) Description and Operation - Engine Control System - Engine Control/Fuel System - Hyundai Azera 2011-2025 Service ManualHyundai Azera: Knock Sensor (KS) Description and Operation

Description
Knocking is a phenomenon characterized by undesirable vibration and noise and can cause engine damage. The two Knock Sensor (KS) are installed inside the V-valley of 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.
