DTC P0125: Insufficient Coolant Temperature For Closed Loop Fuel Control
P0125 - INSUFFICIENT COOLANT TEMPERATURE FOR CLOSED LOOP FUEL CONTROL
| Description: | Indicates the engine coolant temperature (ECT) or the cylinder heat temperature (CHT) sensor has not achieved the required temperature level to enter closed loop operating conditions within a specified amount of time after starting the engine. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | Compare the thermostat specification to the actual engine coolant temperature using the engine temperature PID (ECT or CHT). The temperature reading should be similar when the engine is at a normal operating temperature. | ||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory |
| Vehicles with only a CHT sensor | - | - | GO to Pinpoint Test DL . |
