DTC P0125 Insufficient Coolant Temperature For Closed Loop Fuel Control: DTC Detecting Condition
DTC DETECTING CONDITION CHART
| Item |
Detecting Condition |
Possible Cause |
| 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:
- 2 minutes for intake air temp. > 10°C (50°F)
- 5 minutes 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 |
|
| Fail 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
