| DTC Strategy |
Case1 |
- Plausibility monitoring (low the calibration value of closed position)
|
- Poor connector connection
- Faulty EGR actuator circuit
- Faulty EGR actuator
|
| Case2 |
- Plausibility monitoring (high the calibration value of closed position)
|
| Enable Condition |
- More than 6s after engine "OFF"
- Engine speed is slower than 20 RPM
- Battery voltage is higher than 9V
- Coolant temperature is 0°C to 120°C (32°F to 248°F)
- Intake air temperature is 0°C to 120°C (32°F to 248°F)
|
| Threshold Value |
Case1 |
- Voltage of calibration of EGR closed position is higher than 4.5V
|
| Case2 |
- Voltage of calibration of EGR closed position is lower than 3.5V
|
| Diagnostic Time |
- More than 2s after ignition "OFF"
|
| MIL ON Condition |
