P0125 Insufficient coolant temperature for closed loop fuel control
Check Conditions, Judgement Criteria
Engine coolant temperature decreases from higher than 40°C (104°F) to lower than 40°C (104°F). Then the engine coolant temperature has continued to be 40°C (104°F) or lower for 5 minutes.
Check Conditions, Judgement Criteria
About 60 − 300 seconds have passed for the engine coolant temperature to rise to about 7°C (44.6°F) after starting sequence was completed. However, time is not counted when fuel is shut off.
- Engine coolant temperature sensor failed.
- Open or shorted engine coolant temperature sensor circuit, or loose connector.
- PCM failed.
