| DTC Strategy |
|
- Open in signal harness
- Open in ground harness
- Contact resistance in connectors
- Faulty Heated O2 Sensor (HO2S)
|
| Enable Conditions |
- Sensor preheating and full heating phases finished
- Modeled exhaust gas temp, > 600°C (1112°F)
- Lambda control active
- No relevant failure
- Battery voltage > 10V
|
| Threshold Value |
Case 1) |
- Lambda control not active within the defined time
|
| Case 2) |
- 0,49V > Down HO2S > 0,37V and sensor element resistance > 60 kΩ
|
| Diagnostic Time |
Case 1) |
- 30 ~ 100 sec. depending on start temp.
|
| Case 2) |
|
| Mil On Condition |
