Might be wise to try a local Ford garage and ask if they can advise, some of these Ford engines have more than one, one works the gauge and the other sends information to the ECU for fuel trim data. Important they are all working as you don't want the ECU thinking the car is cooler than it is and richening the mixture to the point where it may over fuel. Some later cars have three sensors. The same place can probably supply a genuine part easier than a factors.
