Its on the block, under neath the airflow bellow.

It kinda helps to remove the plastic electical cover thing from it mounts to get at it.

Thanks for the reply

Does anyone kno if you have to drain any fluids etc from it to change it or is it screw out, screw in?

Cheers

no need to drain the fluid, unless its old. Might loose a bit though, and its probably worth bleeding it after as you may create an air bubble.

Personally I'd take the intake manifold off to make it easier & take the opportunity to replace its gaskets whilst you're at it.

The sensor can be a bugger to get hold off if you lose your grasp on it.

Cool - i have been advised to clean up the throttle body too so may do it all.

Good advice all - thank you.
