DTC P0190: - Fuel Rail Pressure Sensor A Circuit
DTC P0190: - FUEL RAIL PRESSURE SENSOR A CIRCUIT
| Description: | The comprehensive component monitor (CCM) monitors the fuel rail pressure (FRP) sensor to the powertrain control module (PCM) for VREF voltage. The test fails when the VREF voltage from the PCM drops to a voltage less than a minimum calibrated value. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | Verify a VREF voltage between 4 and 6 volts. | ||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory |
