| DTC Strategy |
- Coolant temperature too low for Lambda regulation
|
- Contact resistance in connectors.
- Faulty cooling system.
- Faulty thermostat.
- Faulty ECT sensor.
|
| Enable Conditions |
- Minimum time after engine start versus intake air temperature at start:
- 2minutes for intake air temp. > 10°C(50°F)
- 5minutes for -7°C(19°F) < Intake air temp. < 10°C (50°F)
- 6 < Battery voltage(V) < 16
|
| Threshold value |
- Measured coolant temperature < 5°C(41°F) When modeled coolant temperature > 5°C(41°F)
|
| Diagnostic Time |
|
| Fall Safe |
- Calculated engine coolant temperature is used for engine control.
- Cooling/Condenser fan is active with MAX speed.
- EVAP. emission control function is controlled in minimum operation mode.
