Question about 2003 Ford ZX2
My daughter has a 2001 Ford Escort and the check engine light came on. I connected a buddies code reader to the car and got the code P 0125. I also get the message "Insufficient coolant temp closed loop fuel control"
Can anyone offer a further explanation? I have a 2003 ZX-2 with the same code. I changed the temp sensor and the thermostat. You need a t-25 torx to remove the 3 screws to get at the thermostat, but the sensor is just held in with a pin. Both are located at the front right side of the engine.
Sensor was about $20 and the thermostat and rubber gasket added up to about $10 so I changed both.
This is whats going on insufficient warm up time / low engine coolant /check coolant/ leaking or stuck thermostat or faulty tep sensor
