|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 parameter identification (PID) value during ignition ON, engine OFF or ignition ON, engine running less than 0.3 volt indicates a concern is present.
