Description and operation
Knocking is a phenomenon characterized by undesirable vibration and noise that
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, and the sensor produces voltage signal to ECM. On
receipt of this signal, ECM will control the ignition timing by retarding the ignition
timing and then advancing the ignition timing when the knocking disappears. This
sequential control can improve engine power, torque and fuel economy.

Kia Stinger (CK) 2018-2023 Service Manual: To keep locks from freezing
To keep the locks from freezing, squirt an approved de-icer fluid or glycerine
into the key opening. If a lock is covered with ice, squirt it with an approved
de-icing fluid to remove the ice. If the lock is frozen internally, you may be able
to thaw it out by using a heated key. Handle the heated key with care to avoid injury.
Use approved window washer anti-freeze in system
To keep the water in the window washer system from freezing, add an approved
window washer anti-freeze solution in accordance with instructions on the container.
Kia Stinger (CK) 2018-2023 Service Manual: Electric Power Steering
Description and operation
Description
EPS (Electric power steering, Column assist type) system is an engine operation
independent steering system that uses an electric motor to assist the steering force.
EPS control module controls the motor operation based on input signals from torque
sensor and steering angle sensor via CAN (Controller Area Network), resulting in
a more precise and timely control of steering assist thatn conventional engine-driven
hydraulic systems.
