Kia Forte: Engine Control System / Rail Pressure Sensor (RPS)
Specifications
| Specification |
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
| Inspection |
| 1. |
Connect the KDS on the Data Link Connector (DLC). |
| 2. |
Measure the output voltage of the RPS at idle and various engine speed. |
| Removal & Installation |
| 1. |
Release the residual pressure in fuel line. (Refer to 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 injector foam (A).
|
| 5. |
Disconnect the rail pressure sensor connector (A), and then remove the sensor (B) from the delivery pipe.
|
| 6. |
Install in the reverse order of removal.
