What is it? What does it do? and why have I Had two new ones this year, because they are bloody expensive and I know that the new ones going to break again. :( 1.4 16v 73HP

I may, as always, be wrong but this sounds like what we on t'Interweb call a MAP sensor. Maybe that will throw up some search results.

Thanks I found out what it does and what it is , but I still need to know why mine break, is it because of constant agressive driving?
