Ignore 31 if you didn't have the engine running when you did the test  it will always show up.
15 - Looking into the bay it's on the left hand side below the rad pipe that goes to the thermostat. It's very easy to change, just screws out and new one screws in.
They're about £10 from vauxhall. You may need a long socket to remove it, think i used a spark plug socket for mine.
Check the wiring before replacing the sensor though, the movement of the engine can break the wire so check for splits and breaks first.

Does the engine management light come on when you're driving it or did you just flash the codes for the sake of it?
If it is cutting out, it may be worth trying another crank sensor aswell. They're a common failure.
Try clearing the codes (battery off for an hour) then drive the car until EML comes on.
Then do another Paperclip test with the engine running and see if it still says crank sensor?

Only one worth worrying about there is the coolant sensor.. If thats failed it will cause cold or warm starting problems, plus lump idle .
