Description and operation

Description

Installed on the delivery pipe, the Rail Pressure Sensor (RPS) measures the instantaneous fuel pressure in the delivery pipe. The sensing element (semiconductor element) built into the sensor converts the pressure to voltage signal. By using this signal, the ECM controls the correct injection amount and timing and adjusts the fuel pressure with the fuel pressure regulator valve if the actual pressure calculated by the RPS output signal is different from the target pressure.

Repair procedures

Inspection

1.	Connect the KDS on the Data Link Connector (DLC).

Measure the output voltage and fuel pressure of the RPS at idle and various engine speed.

Pressure		Output Voltage (V) [Vref=5V]
bar	[MPa (kgf/cm², psi)]	Output Voltage (V) [Vref=5V]
0	0 (0, 0)	0.5
140	14 (142, 2031)	2.5
280	28 (286, 4061)	4.5

Removal

1.	Release the residual pressure in fuel line. (Refer to the Fuel Delivery System - "Release Residual Pressure in Fuel Line")

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

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

4.	Remove the delivery pipe foam (A).

5.	Disconnect the rail pressure sensor connector (A), and then remove the sensor (B) from the delivery pipe.

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: Electro Chromic Inside Rear View Mirror

Components and components location Components Description and operation Description The ECM (Electro Chromatic inside rear view Mirror) is one that automatically dims to protect the driver’s eyes when it senses light reflecting from the car behind. The sensor in the mirror detects the brightness and if the headlight from the car behind is reflected on the mirror, the chemical layer inside the mirror reacts to glare and adjusts the reflectivity from 10 to 70%.
