Fuel low-pressure sensor: Notes
WARNING: This page does not describe the selected car, but rather 45 other vehicles, including the 2016 BMW M5, 2016 BMW 550i xDrive, 2016 BMW 550i, 2016 BMW 535i xDrive, and 2016 BMW 535i. However, it is still accessible from the selected car via links, so may be relevant.
The fuel low-pressure sensor is screwed into the fuel delivery line between both of the high pressure pumps.
The fuel low-pressure sensor monitors the pressure of the fuel in the supply line. The fuel is delivered by the fuel pump in accordance with requirements.
The fuel low-pressure sensor serves the electric fuel pump control unit (EKPS). The analogue output signal is evaluated by the engine controller.
