P0125 - Insufficient Coolant Temp For Closed Loop Fuel Control

P0125 - INSUFFICIENT COOLANT TEMP FOR CLOSED LOOP FUEL CONTROL

Description:  This DTC sets when the engine coolant temperature (ECT) or the cylinder head 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: 
  • Insufficient warm up time
  • Low engine coolant level
  • Leaking or stuck open thermostat
  • Damaged ECT sensor
  • Damaged CHT sensor
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.
