Fuel Pressure Sensor
WARNING: This page does not describe the selected car, but rather 31 other vehicles, including the 2015 Lincoln Navigator, 2015 Lincoln MKZ, 2015 Lincoln MKX, 2015 Lincoln MKT, and 2015 Lincoln MKS. However, it is still accessible from the selected car via links, so may be relevant.
The fuel pressure sensor (located in the fuel line either near the fuel tank or near the engine) provides a pressure feedback signal for the low pressure fuel system to the PCM. The PCM uses the FLP signal to determine correct operation of the low pressure fuel system.
