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 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 | |
| All | refer to PINPOINT TEST DD . | |||
