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.
P0192 - FUEL RAIL PRESSURE SENSOR A CIRCUIT LOW

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