Description and operation

Description

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.

Repair procedures

Inspection

1.	Switch "OFF" the ignition.

2.	Disconnect the knock sensor connector.

3.	Measure resistance between the injector terminals 1 and 2.

Check that the resistance is within the specification.

Specification: About 4.87 MΩ [20°C(68°F)]

Removal

1.	Switch "OFF" the ignition and disconnect the negative (-) battery terminal.

2.	Remove the intake manifold. (Refer to Engine Mechanical System - “Intake Manifold”)

3.	Remove the delivery pipe & injector assembly. (Refer to Fuel Delivery System - "Delivery Pipe")

Remove the knock sensor (A) after loosening the mounting bolt from the cylinder block.

Knock sensor installation bolt :

18.6 - 23.5 N·m (1.9 - 2.4 kgf·m, 13.7 - 17.4 lb·ft)

Installation

•	Install the component to the specified torques.

•	Note that internal damage may occur when the component is dropped. If the component has been dropped, inspect before installing.

1.	Install in the reverse order of removal.

Kia Stinger (CK) 2018-2023 Service Manual: Side Impact Sensor (SIS)

Description and operation Description • Side Impact Sensor (SIS) system consists of two Pressure Side Impact Sensor (P-SIS) installed at each center of the front door module (LH and RH), two SIS installed at each center pillar nearby (LH and RH) and two rear SIS installed in the rear pillar (LH and RH). • Pressure Side Impact Sensor is also called P-SIS because it detects pressure from collision at its mounting location.
