Hyundai Tucson: Engine Control System / Rail Pressure Sensor (RPS) Repair procedures
| 1. |
Connect the GDS on the Data Link Connector (DLC). |
| 2. |
Measure the output voltage of the RPS at idle and various engine speed.
Condition
| Output Voltage (V)
| Idle
| Approx. 1.2
| 1,500 rpm
| 2.2 ~ 2.5
| 6,300 rpm
| Approx. 3.0
|
|
| 1. |
Turn the ignition switch OFF and disconnect the battery negative (-) cable. |
| 2. |
Release the residual pressure in fuel line.
(Refer to the 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 GDS after completion of
“Release Residual Pressure in Fuel Line” work. |
|
| 3. |
Remove the intake manifold.
(Refer to Engine Mechanical System - “Intake And Exhaust System”) |
| 4. |
Remove the injector foam (A). 
|
| 5. |
