DTC P0192: Fuel Rail Pressure (FRP) Sensor Circuit Low Input

WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
P0192 - FUEL RAIL PRESSURE (FRP) SENSOR CIRCUIT LOW INPUT

Description:  The comprehensive component monitor (CCM) monitors the FRP sensor circuit to the PCM for low voltage. If voltage falls below a calibrated limit and a calibrated amount of time during testing, the test fails.
Possible Causes: 
  • FRP signal shorted to SIG RTN or PWR GND.
  • Damaged FRP sensor.
  • VREF circuit open.
  • VREF circuit shorted to GND or SIGRTN.
  • Damaged PCM.
Diagnostic Aids:  An FRP PID value less than 0.3 volt during KOEO or KOER indicates a hard fault.
