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.
