| DTC Strategy |
- Monitor the fuel rail/system pressure - too low
|
- A leaky injector, a leak in the fuel rail
- Mechanical failure in high pressure pump
- Sticking by low pressure of rail pressure sensor
- Fuel supply system (low line) error
|
| Case1 |
Enable Condition |
- Engine speed is between 512 RPM and 6816 RPM
- Mass fuel flow is between 0.012g/revolutions and 0.36g/revolutions
- Time after engine start is greater than 15s
- Volume of fuel flow is less than 14.5 to 216 (l/h)
|
| Threshold Value |
- Delivery of high pressure pump is too low
|
| Diagnostic Time |
|
| Case2 |
Enable Condition |
- Engine speed is between 512 RPM and 6816 RPM
- Mass fuel flow is between 0.012g/revolutions and 0.36g/revolutions
- Time after engine start is more than 15s
- Volume of fuel flow is less than 14.5 to 216 (l/h)
|
| Threshold Value |
- Delivery of high pressure pump is too low or over pressure valve is defect
|
| Diagnostic Time |

- Volume of fuel flow is less than 14.5 to 216 (l/h)
- Mass of fuel flow is greater than 0.012g/revolutions
- Engine speed is faster than 512 RPM
|
| Threshold Value |
- Fuel pressure during catalyst heating is too low
