S40 fuel pressure S40-V40

First post on this forum. I see there is an old thread related to this, but no activity for a year, so I'll try a new one. My 2005 s40 t5 manual throws code p0089 from time to time. Seems to run ok. I replaced the fuel rail pressure sensor but the code came back a week later. My scanner shows FRP around 309kPa running at idle. I don't have a fuel pressure guage. Could the MAP sensor be faulty? Fuel pump problem? How to tell?
Also, can anyone tell me if the fuel pump on this car is only accessible by dropping the tank, as Haynes says, and you need to cut up the exhaust system to do that? That sounds really nasty. There is no access to the fuel pump under the back seat.

I'd be happy for advice.

    Since there were no answers to my post, I'll provide an update. The MAP sensor (AKA turbo boost sensor) on the 2005 S40 t5 is located on the passenger (right) side of the intercooler. Pop the plastic panel off the right hand fog light and you're looking at it. I changed this and have not seen a CEL for the last week. Here's hoping!

      Since I see that several people have read this thread, although not a soul has responded, I'll again update my own post.
      The MAP sensor (turbo boost sensor) did not fix the problem and the CEL and P0089 came right back. So I undertook to replace the fuel pump module, which requires pulling off the heat shielding & dropping the fuel tank! Not my favourite job. It would not be bad if you had a hoist. However, it has now been about 10 days and many highway and city kms. with no sign of a CEL or code, so I think it is fixed. I have not yet done a post-mortem on the old pump, so can't tell you what went wrong. The new one is an OEM Bosch module (pump, filter, and fuel guage sender) from Rock Auto. The price was about $250 Can and their delivery speed is amazing-- about 4 days to Alberta! Cheers!
