P119C INFINITI Meaning

The fuel rail pressure (FRP) sensor is placed to the fuel rail and measures fuel pressure in the fuel rail. The sensor transmits voltage signal to the Engine Control Module (ECM). As the pressure increases, the voltage rises. The ECM controls the fuel pressure in the fuel rail by operating high pressure fuel pump. The ECM uses the signal from fuel rail pressure sensor as a feedback signal.
The Engine Control Module (ECM) monitors the Fuel Rail Pressure Sensor. The ECM sets the OBDII code when the Fuel Rail Pressure Sensor is not to factory specifications.
