Fifth generation HG (2011–2026) / Hyundai Azera 2011-2026 Service 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. 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.
