Kia Sportage: Engine Control System / Rail Pressure Sensor (RPS) Repair procedures

Kia Sportage QL (2015-2026) Service Manual / Engine Control / Fuel System / Engine Control System / Rail Pressure Sensor (RPS) Repair procedures

Inspection

1.	Connect the KDS/GDS 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.	Turn the ignition switch OFF and disconnect the battery negative (-) 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 with the specified torques.

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

Install in the reverse order of removal.
