Description and operation
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.

Repair procedures
1. |
Connect the KDS on the Data Link Connector (DLC).
|
2. |
Measure the output voltage and fuel pressure of the RPS at idle and various
engine speed.

|
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.

|
• |
Install the component to the specified torques.
|
• |
Note that internal damage may occur when the component is dropped.
If the component has been dropped, inspect before installing.
|
|
1. |
Install in the reverse order of removal.
