P0192 - Fuel Rail Pressure Sensor A Circuit Low

WARNING: This page does not describe the selected car, but rather 32 other vehicles, including the 2007 Mercury Mountaineer, 2007 Mercury Monterey, 2007 Mercury Montego, 2007 Mercury Milan, and 2007 Mercury Mariner. 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 powertrain control module (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: 
  • FRP signal short to SIG RTN or PWR GND
  • Damaged FRP sensor
Diagnostic Aids:  A FRP PID value during key ON, engine OFF or key ON, engine running less than 0.3 volt indicates a concern is present.
Application  Key On Engine Off  Key On Engine Running  Continuous Memory
