| DTC Strategy |
- Coolant Temperature too low for Lambda regulation
|
- Poor connector connection
- Faulty cooling system
- Open or short in ECT sensor signal circuit
- Faulty ECT sensor
|
| Enable Conditions |
- ECT at engine start lower than 0°C (32°F)
- 50s elapsed after start when difference of Lambda control enable ECT and ECT at start is 0°C (32°F)
- 100s elapsed after start when difference of Lambda control enable ECT and ECT at start is 8°C (46°F)
- 200s elapsed after start when difference of Lambda control enable ECT and ECT at start is 20°C (68°F)
- 300s elapsed after start when difference of Lambda control enable ECT and ECT at start is 35°C (95°F)
- Battery voltage higher than 11V and lower than 16V
- No relevant DTC present
