Ok guys fairly new to the forum with my focus ST225 and currently have a problem which i believe is down to the MAP sensor. I think the connection may have got a bit wet after i stupidly went through a flood. Basically the oil temp gauge works fine then randomly goes to 0 as if the engine was off and the oil pressure stays around 4 and 5 bar. This is only intermittent and sometimes doesn't happen at all, however today it played up a little then went back to normal after a few miles. What i need t know from you guy is do you have any step by step guides or clear pictures of where it is. I have taken the os drivers light off which is what i was told but my mechanical knowledge of these things is awful and really dont want to disconnect something i shouldn't. Thanks

 

It's in the pipe just below the OS headlight, IIRC a torx bolt holding it in TX25 or TX30 (possibly)

Looks like this http://j-w-racing.co.uk/product.php/..._ford_focus_st

As long as ignition is off it's fine to disconnect it.

 

Thanks mate will give a go today.
