I tried this, it was a ballache, so I took off the inlet manifold, it is pretty easy to remove.
I did a guide to remove the TB and clean it:

So going off that you don't even need to remove the TB from the manifold, but use it to remove the inlet pipe to TB then undo all the bolts holding the inlet on, as 19Zen said remove the dipstick bolt and it makes it a hell of a lot easier (I have massive spades for hands, so just couldn't get to the sensor with the inlet in the way).
