Hyundai Ioniq: 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 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. |

| 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. | Install in the reverse order of removal. Rail pressure sensor installation : 30.0 - 35.0 N.m (3.0 - 3.6 kgf.m, 22.1 - 25.8 lb-ft) |
