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 |
- Coolant temperature at Start < close loop enable ECT
- Modeled coolant temperature > 20°C (68°F)
- After 100~1000 seconds from engine start
|
| Threshold value |
- Measured coolant temperature< threshold When modeled coolant temperature > threshold
|
| Diagonostic 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.
