Thank You for your reply. They say this because they are not able to find any other cause , they have checked the physical parts (Engine Coolant Temperature (ECT) sensor) and wiring and say they are all ok. Also i think they dont have information for PCM, so the easist solution is to replace it.
Yes, maybe you are right, i have to go to the offical ford dealer. However the one that is here is very expensive for a ford fiesta of 1997 :) this is why i was thinking about any software that will me let reconfigure the PCM (i think, maybe i am wrong, the PCM get the right temperature from the sensor but its "logic" is wrong and it triggers the coolant)
