| DTC Strategy |
|
- Poor connection or damaged harness
- EGR cooler clogging
- EGR pipe clogging and leakage
- Intake manifold air leak
- EGR actuator stuck
|
| Enable Condition |
- Fuel cut - Off condition
- EGR valve position study is completed
- No relevant failure
- Intake air temperature is higher than -6.75°C (19.85°F)
- Engine coolant temperature is higher than 54°C (129°F)
- Engine RPM ranges from 1088RPM to 2016RPM
- Mean engine RPM ranges from-192RPM/s to 192RPM/s
- Barometric pressure is higher than 74 kPa
- Battery voltage between 11V and 16V
- Intake manifold pressure is higher than 100 hPa
- Throttle position ranges from 0° to 23.8 to 24.1° (depends on engine RPM and intake air temperature.)
- EGR recirculation flow is higher than 5kg/h
|
| Threshold Value |
- Comparing the reference pressure and a measured pressure is higher than 1.45
- Intake manifold pressure is lower than 41 to 112 kPa (EGR valve close)
|
| Diagnostic Time |
- Fuel cut off duration 10s
|
| MIL ON Condition |
