Description and operation
| Description |
Installed on the delivery pipe, the Rail Pressure Sensor (RPS) measures the instantaneous fuel pressure in the delivery pipe. The sensing element (semiconductor element) built into the sensor converts the pressure to voltage signal. By using this signal, the ECM controls the correct injection amount and timing and adjusts the fuel pressure with the fuel pressure regulator valve if the actual pressure calculated by the RPS output signal is different from the target pressure.

| Removal |
| 1. |
Release the residual pressure in fuel line. (Refer to the Fuel Delivery System - "Release Residual Pressure in Fuel Line") |
| 2. |
Switch "OFF" the ignition and disconnect the negative (-) battery terminal. |
| 3. |
Remove the intake manifold. (Refer to Engine Mechanical System - “Intake Manifold”) |
| 4. |
Remove the delivery pipe foam (A).
|
| 5. |
Disconnect the rail pressure sensor connector (A), and then remove the sensor (B) from the delivery pipe.
|
| Installation |
|
| 1. |
Install in the reverse order of removal. |
