A fuel pressure sensor is responsible for metering the fuel pressure inside your fuel rail, and reporting back to the ECM (engine control module). The ECM then takes this value and uses it in conjunction with engine load and other metrics to determine the amount of current required by the fuel pump to keep up with demand.
A faulty fuel pump or a clogged fuel filter causes lower than normal fuel pressure. Proper fuel pressure is vital for engine operation and performance. Check with the manufacturer's manual for special procedures. Some fuel pressure regulators are electric and controlled by a control module (PCM).
