need help changing map sensor volvo s40 2000
Hi, I need help changing the map sensor in my volvo s40 2000. I have located it between the 3rd and 4th rail but I can't remove the fuel rail. I am too scared to mess anything there without knowing how to get it out. I can't reach the bolt in the MAP sensor (maybe I need a better wrench?) The wrench I have is too tall to reach in between the long metal rail and the map sensor.

The sensor is located in the red box below. Not sure how to remove it, but I am guessing it is pretty straight forward. I will look today and maybe take a few pictures.

I looked at your pics again and then checked my car again. (Mine is a 2001) It appears mine does have a second MAP sensor a little further up the tube just above the temp sensor where yours does not. I didn't realize there were any changes between the 2000 and 2001 models.
I am definetly no expert on this subject. My dealer showed me the schematics for both MAP sensor locations and they both showed the same part number. Apparently one measures boost and the other barometric pressure. I wasn't sure which one to replace first but I started with the one on the intake manifold and luckily found the problem there. Didn't have to touch the one above the intercooler.
It is still amazing to me that I fought this problem for so long and had the dealer quote me such an outrageous price only to fix it myself for $82 and 10 minutes later with a stupid little electrical sensor. (Once I found the actual MAP sensor locations that is). My car has been running great ever since.
