The fuel pressure sensor measures the amount of pressure present in your fuel lines, and sends this information back to the ECU. If a problem arises with the amount of fuel pressure, the sensor will alert the ECU, which in turn, will alert the driver. Usually with a loss of fuel pressure it can be a faulty pressure sensor, a fuel pump, or a clogged fuel filter. Replace your faulty pressure sensor and get your vehicle back to excellent running condition.

Be sure to check out ECS' fuel filters and fuel pumps also, to ensure everything is running correctly.
