| DTC Strategy |
- Coolant temperature too low for lambda regulation
|
- Poor connector connection
- Faulty cooling system
- Open or short in ECTS signal circuit
- Faulty ECTS
|
| Enable Condition |
- ECT at engine start less than 5.25°C (41°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 5.3°C (41°F)
- 200s elapsed after start when difference of lambda control enable ECT and ECT at start is 15°C (59°F)
- 300s elapsed after start when difference of lambda control enable ECT and ECT at start is 30°C (86°F)
- Normal auxiliary battery voltage (11 to 16V)
- No relevant DTC present

| Threshold Value |
- Coolant temperature remains less than 3°C (37.4°F) after engine start
