DTC P0125 Insufficient Coolant Temperature For Closed Loop Fuel Control: DTC Detecting Condition
DTC DETECTING CONDITION CHART
| Item |
Detecting Condition |
Possible Cause |
| DTC Strategy |
- Check time to closed loop control start with coolant temperature model.
|
- 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 :
- 2 minutes for intake air temperature > 10°C (50°F)
- 5 minutes for -7°C (19°F) < Intake air temperature < 10°C (50°F)
- 6 < Battery voltage (V) < 16
- Elapsed time after Start versus Engine coolant temperature at start
- 2 minutes for intake air temperature > 10°C (50°F)
- 5 minutes for -7°C (19°F) < Intake air temperature < 10°C (50°F)
|
| 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.
