Ford Repair Questions? Ask a Mechanic for Answers ASAP
hi thanks a mill plenty of checking to do but just a couple of questions 1 can the crank shaft sensor be fitted withoiut opening the gearbox 2 why is the fan continuously on when new engine started . why when car started initially display light orange on dash refrred to in book as engine mal fuction.
The ECU senses this and may put the car into 'limp home' mode which typically limits the revs and the amount of power available. Usually the car is safe to drive for a short distance as the mode is intended is intended to get you home without incurring any engine damage
The quickest route to repair is to have the car plugged into a diagnostic machine which will read off the fault code stored in the ECU (providing the light is still on at this point) and indicate which sensor has failed or whether the fault is more serious.
Hi Mat thanks a million for your brilliant reply and quick responce but I am still pulling my hair out at this atage for the following reason. I got a top diagnostic man that put his computor on the car,He then stated that it was showing two faults a heater sensor and an injector problem.He said that there was great diesel pressure on the injectors he could not say which injector.He advisedcx that my mechanic go through the car inc by inch checking every connection including the timing setting.He said tht it was very hard to find a problem with the engine not running this must be a joke I thought to myself.Lastly he said that Ford would probably have a better computor for checking out the problem. So I spoke to my mechanic and he said definitely not a timing problem but in due course will check all connections meanwhile my Mondeo lies in garage not starting.The diagnostic man said sensor failure would not stop the car from starting is this correct. Thanks Val
hi mat just one question does the crank sensor need special setting as there is room for manouvering on the bracket please
hi mat thanks for that reply new sensor not installed yet awaitibg same fro ford.Last Saturday my mechanic checked injectors while turning engine and their seemed to be little pressure on them no squirting out just a weak dribble.Would this be caused by sensor malfunction or is the ecu not allowing the car to start until sensors are replaced please.
hi Mat Thanks a mil you were spot on about the crank sensor.I bought a new crank sensor my mechanic fitted it and the car started immediately great. Now the final touches the fan is continuously on and the diagnostic man cannot find a fault ,The panel still shows an engine fault.The light weas cleared but came back on soon afterwards.We checked the connections leading to a small steel unit attached to the fan and they are ok.What is this small square unit and is it possible that this is faulty,I dont know what it is called.Also the power steering is whiney we put oil to the correct level I wonder should we replace the old oil altogether as the car was lying up for about eighteen months. Thanks
