DTC P0125 : Check Engine Coolant Level

This DTC indicates ECT sensor has not reached the required temperature level to enter closed loop operating conditions within a specified amount of time after starting engine. Possible causes for this fault are: Insufficient Engine Warm-Up Time
Thermostat Leaking Or Stuck Open
Malfunctioning CHT Or ECT Sensor
Low Coolant Level

Check and repair cooling system as necessary.

A Cylinder Head Temperature sensor is used instead of an ECT.
