Description and operation
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 into the sensor converts the pressure to voltage signal. By using this signal,
the ECM controls the correct injection amount and timing and adjusts the fuel pressure
with the fuel pressure regulator valve if the actual pressure calculated by the
RPS output signal is different from the target pressure.
