Hyundai i-30: Engine Control System / Rail Pressure Sensor (RPS)
Description and operation
Rail Pressure Sensor (RPS) is installed on the delivery pipe and measures the
instantaneous fuel pressure in the delivery pipe. The sensing element (Semiconductor
element) built in the sensor converts the pressure to voltage signal. By using
this signal, the ECM can control correct injection amount and timing and adjusts
the fuel pressure with the fuel pressure regulator valve if the target pressure
and the actual pressure calculated by the RPS output signal are different.

1. |
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 diagnostic
tool after completion of "Release Residual Pressure
in Fuel Line" work.

|
2. |
Turn the ignition switch OFF and disconnect the battery negative (-)
cable.
|
3. |
Remove the intake manifold
(Refer to Engine Mechanical System - "Intake Manifold")
|
4. |
Disconnect the rail pressure sensor connector, and then remove the sensor
(A) from the delivery pipe.
