My wifey owns a Focus 2.0l 16v. Currently not running, hence my joining forum to see if I can find solution. I too suffered the same problem of not being able to open what could be a very useful diagram of where to find the cam/crankshaft sensor, so please excuse me while I make a few inane posts to be able to open that jpeg. My own motor is a Freelander - so I won't bore you. But I have found user forums to be invaluable with help on mine.
