not too sure where they are but ive the same problem mines a 2001 1.6 and was told its quite tricky to get too, any car manufactured after 2001 apparently its easier to get to? so gonna have to pay thru the the nose to get it fixed. car keeps cutting out on idle and losing power so best to get it changed. was told by one garage you may be able to get it cleaned instead of buying a new one which i believe is about £120 just for the part. hope this helps
