Kia Sportage: Rail Pressure Sensor (RPS)

Kia Sportage Third generation (SL) - (2011-2016) - Service and Repair Manual / Fuel System / Engine Control System / Rail Pressure Sensor (RPS)

Description and Operation

 Description

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.

Repair procedures

Repair procedures

Inspection

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

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

Removal

Removal

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

2. Release the residual pressure in fuel line (Refer to "Release Residual Pressure in Fuel Line" in this group).

CAUTION

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 "Intake And Exhaust System" in EM group).

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

Installation

Installation

CAUTION

  • 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.

1. Installation is reverse of removal.

Rail Pressure Sensor Installation: 18.0 ~ 22.0 N.m (1.8 ~ 2.2 kgf.m, 13.3 ~ 16.2 lb-ft)
