This low pressure fuel sensor is located on the high pressure fuel pump. It measures the low fuel pressure at the pump, 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.
