| DTC Strategy |
- Timer increase check after engine stop

| Enable Condition |
Case1 |
- Warmed up condition met at previous driving cycle
- ECT at previous driving cycle is greater than 70°C (158°F)
- The difference between the intake air temperature at the time of the last ignition switch "OFF" and the intake air temperature at the current ignition switch "ON" is greater than 0°C (32°F)
- The difference between the coolant temperature at the time of the last ignition switch "OFF" and the coolant temperature at the current ignition switch "ON" is greater than 40°C (104°F)
- No fault related to intake air temperature sensor and coolant temperature sensor

| Case2 |
- Warmed up condition met at previous driving cycle
- ECT at previous driving cycle is greater than 70°C (158°F)
- The difference between the intake air temperature at the time of the last ignition switch "OFF" and the intake air temperature at the current ignition switch "ON" is greater than 40°C (104°F)
- The difference between the coolant temperature at the time of the last ignition switch "OFF" and the coolant temperature at the current ignition switch "ON" is greater than 30°C (86°F)
- No fault related to intake air temperature sensor and coolant temperature sensor
