Kia Carens: Engine Control System / Rail Pressure Sensor (RPS) Description and operation
Rail 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. By using
this signal, the ECM can control correct injection amount and timing and adjusts
the fuel pressure with the fuel pressure regulator valve if the target pressure
and the actual pressure calculated by the RPS output signal are different.
