Function of the fuel low pressure sensor
The fuel low-pressure sensor plays an important role in a car's fuel supply system. It monitors the pressure in the fuel supply system, typically in the area between the fuel tank and the high-pressure pump.
The sensor continuously provides data to the engine control unit, which uses this information to optimally control the fuel supply and ensure efficient engine operation. Correct fuel pressure is critical because it affects the amount of fuel injected and thus engine performance and emissions. A malfunction of the sensor can lead to irregular engine running, loss of power or increased emissions.
