P018C - Fuel Pressure Sensor B Circuit Low

WARNING: This page does not describe the selected car, but rather 28 other vehicles, including the 2014 Lincoln Navigator, 2014 Lincoln MKZ, 2014 Lincoln MKX, 2014 Lincoln MKT, and 2014 Lincoln MKS. However, it is still accessible from the selected car via links, so may be relevant.
P018C - FUEL PRESSURE SENSOR B CIRCUIT LOW

Description:  The comprehensive component monitor (CCM) monitors the FLP circuit to the PCM for low voltage. The test fails if the voltage falls below a calibrated limit for a calibrated amount of time during testing.
Possible Causes: 
  • FLP signal short to SIGRTN or GND
  • Damaged fuel pressure sensor
Diagnostic Aids:  An FLP PID value during ignition ON, engine OFF, or ignition ON, engine running, less than 0.3 volt indicates a concern is present.
