Fuel Rail Pressure Control (Cranking)
The engine is designed to start with a minimum required fuel injection pressure. If that minimum fuel injection pressure is not achieved before the first fuel injection, a fault is set.
FUEL RAIL PRESSURE CONTROL (CRANKING) FUNCTIONAL CHECK OPERATION
| DTCs | P00C6 (Fuel Rail Pressure Too Low - Engine Cranking) |
| Monitor execution | Minimum pressure met instantaneously once during cranking |
| Monitor Sequence | P0087 and P0088 must pass before setting P00C6 or P053F |
| Sensors/Actuators OK | FLI, FRP, FVR,, Lift Pump |
| Monitoring Duration | Minimum met instantaneously once during cranking |
TYPICAL FUEL RAIL PRESSURE CONTROL (CRANKING) FUNCTIONAL CHECK ENTRY CONDITIONS
| Entry Condition | Minimum | Maximum |
| Fuel Level | 15% |
TYPICAL FUEL RAIL PRESSURE CONTROL (CRANKING) FUNCTIONAL CHECK MALFUNCTION THRESHOLDS
| Fuel_Pressure_Actual >= Fuel_Pressure_Desired |
