The Fuel Pressure Sensor -G247- (rail pressure sensor) is located inside the left high pressure reservoir (cylinder bank 2) and measures the current fuel pressure in the high pressure system and sends a voltage signal to the Engine Control Module -J623- .
If the sensor malfunctions, the pressure is controlled via an engine control module characteristic map. The maximum engine speed is limited to approximately 3000 RPM in emergency mode.
