Question about 2001 Ford Escort ZX2

1 Answer

Escort check engine light - code = P0125

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 replaced the thermostat and keep getting the P0125 code. My car runs rough, I think it might have something to do with the O2 sensor not working right, maybe not getting up to temp?

Sounds as if the car is not getting warm enough, which could mean that your thermostat is stuck in the open position. Try changing it. That should take care of the problem. Depending on which brand you get, the thermostat will most likely cost you between $8.00-$16.00.

Also, check the coolant level. Make sure its at a proper level. The Temperature Sensor could be bad as well.

2001 ford taurus with check engine light on. code


Make sure you replaced the right one there are two sensor's for the coolant, one takes coolant temp and the other one runs the fans for the radiator. Both are located on drivers side of the block. 2 wire leads on each how ever both are different in sending readings to the computer.Both look just alike also. Just make sure you replaced the right one. Or replace both.

Take it to Autozone, they will hook up a code reader for free, they will tell you why the light came on. Before you take it, make sure your gas cap is on tight. Thats a major reason that the light comes on.
