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
