| DTC Strategy |
|
- Poor connection or damaged harness
- EGR cooler cloggging
- EGR pipe clogging and leakage
- Intake manifold air leak
- EGR actuator stuck
|
| Enable Conditions |
Case 1 |
- Activated EGR valve control
- Time after engine start is more than 20 sec.
|
| Case 2 |
- Engine coolant temp. is greater than 55°C (131°F)
- Ambient air temperature is greater than 9.8 °C (49.64°F)
- Battery voltage is higher than 5V
|
| Threshold Value |
Case 1 |
- PWM value for valve control is higher than 99%
|
| Case 2 |
- PWM value for valve control is lower than -99%
