TYPICAL VOLUME CONTROL VALVE MONITOR MALFUNCTION THRESHOLDS
| P0001
- IIf the volume control valve is not energized and the voltage from the volume control valve control chip is in the range 2.8 - 4.8 V (normal operation: 5V secondary voltage supply) P0002 - Temperature of powerstage driver on ECM > 170 deg C (6.7L only) P0003 - If the volume control valve is not energized and the observed voltage from the volume control valve control chip is less than 2.8V (normal operation: 5V secondary voltage supply) P0004 - If the volume control valve is energized and the current to the volume control valve exceeds 3.7A (normal operation: 2.2A maximum) |
FUEL VOLUME REGULATOR CONTROL VALVE (VCV) MONITOR OPERATION
| DTCs | P000E - Fuel Volume Regulator Control Exceeded Learning Limit P228D - Fuel Pressure Regulator 1 Exceeded Control Limits - Pressure Too High |
| Monitor Execution | Continuous |
| Monitor Sequence | None |
| Sensors OK | P000E: None P228D: VCV (P0001, P0003, P0004), FRP (P0191, P0192, P0193, P0194), Sensor Reference Voltage "B" (P0652, P0653) |
