Hyundai Ioniq (AE): Engine Control System / Rail Pressure Sensor (RPS)

Inspection1.Turn ignition switch OFF.2.Disconnect the connector of exhaust gas temperature sensors #1/#2.3.Measure resistance between sensor signal terminal and ground terminal.

DescriptionRail 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.
