I have a 16V-Zetec ZTS Ford Focus. Car is running rough. Skipping and bucking during acceleration. Weather has turned cooler and car is beginning to idle rough also. Check engine light is on. Code P0125. Coolant Temp Sensor. Cant find the sensor to replace.

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.
