Quite probably the only cleaning possible is that of the external connectors. Basically inside the tps there is a potentiometer and one possible cause for failure could be the 'wiping' brush and 'track' have worn. Then again it could be more advanced. All very tentative but that's all I've got on that! I have seen programmes where the tips has been overhauled and modernised such as on Maseratis. Have a look online for the tips you could be lucky and I might not be that expensive, hopefully.
I've been looking online, as jomper says it is the whole unit. There are pre-owned bodies on eBay at reasonable prices but you'll need the part number from the side of the throttle body and will be a gamble. Wide range of prices for new from £120 to much more, and again non Bosch could be a gamble. Try what jomper says before shelling out.
