Kia Cadenza YG 2016-2025 Service Manual / Engine Control / Fuel System / Engine Control System / Rail Pressure Sensor (RPS) Repair procedures

Inspection

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

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

Condition	Output Voltage (V)
Idle	Approx. 1.2
1,500 rpm	2.0 ~ 2.2
6,300 rpm	Approx. 2.8

Removal

1.	Turn the ignition switch OFF and disconnect the battery negative (-) cable.

Release the residual pressure in fuel line.

(Refer to the Fuel Delivery System - Repair Procedures - "Release Residual Pressure in Fuel Line").

When removing the fuel pump fuse, a Diagnostic Trouble Code (DTC) may occur. Delete the code with the GDS after completion of “Release Residual Pressure in Fuel Line” work.

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

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

Installation

•	Install the component with the specified torques.
