DTC P0190: Fuel Rail Pressure (FRP) Sensor Circuit Malfunction
WARNING: This page is about a different variant/trim than selected.
P0190 - FUEL RAIL PRESSURE (FRP) SENSOR CIRCUIT MALFUNCTION
| Description: | The comprehensive component monitor (CCM) monitors the 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 |
