Kia Cee'd Service Manual / 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	2.2 ~ 2.5
6,300 rpm	Approx. 3.0

Removal

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

Release the residual pressure in fuel line.

(Refer to Fuel Delivery System - "Release Residual Pressure in Fuel Line")

When removing the fuel pump relay, 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")
