P0192 - FUEL RAIL PRESSURE SENSOR A CIRCUIT LOW
| Description: | The powertrain control module (PCM) continuously monitors the fuel rail pressure (FRP) sensor input to determine if the FRP signal is within an expected range. The test fails when FRP voltage is lower than expected. | |||
| Possible Causes: |
|
|||
| Diagnostic Aids: | With the key ON, engine OFF verify that the VREF voltage at the FRP sensor is between 4 and 6 volts. | |||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory | |
