DTC 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: |
|
||
| 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. | ||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory |
| All | GO to PINPOINT TEST DD . | ||
