Kia Niro: Engine Control System / Rail Pressure Sensor (RPS) Description and operation
| Description |
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 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 is different from the actual pressure calculated by the RPS output signal.
