DTC P0193: - FUEL RAIL PRESSURE SENSOR A CIRCUIT HIGH
| Description: | The comprehensive component monitor (CCM) monitors the fuel rail pressure (FRP) sensor circuit to the powertrain control module (PCM) for high voltage. The test fails if the voltage exceeds a calibrated limit for a calibrated amount of time during testing. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | An FRP signal high condition can be caused by any number of conditions, including a short on FRP signal to VREF, a more positive voltage level, an open FRP signal or signal return. The FRP signal line is pulled up by the PCM and VREF at the sensor, and down by the sensor through SIGRTN. | ||
