Might want to add it's the near side rear sensor you need man!
'On two occasions I have been asked, 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.' - Charles Babbage
And just so you know, so long as it's from the correct corner, it can be off any 4th gen (engine, gearbox, year etc. make no difference).
At a push, the rear sensors are interchangeable side-side but there is faff involved and risk of damaging the cable, so best avoided if poss. Front/rear are not interchangeable.
Give the cable bracket bolts a good long soak with wd40 and some good hard taps before you try to undo them, otherwise they will shear off (corrosion round the threads)...
