Fuel System 127 Diesel Control System
Rail Pressure Sensor (RPS)
Function And Operation Principle
The Rail Pressure Sensor (RPS) is installed at the end of the common rail (bank 1) and measures the
instantaneous fuel pressure in the common rail. The sensing element (semiconductor device) built in the
sensor converts the pressure to voltage signal. By using this signal, the ECM can control correct injection amount
and timing. And it adjusts the rail pressure with the rail pressure regulator valve if the target pressure and the actual
pressure calculated by the RPS output signal are different.
