2005 S40T5 map sensor

Post by ehirsh » Thu Oct 10, 2019 5:43 pm

2005 S40 T5 2.5 - I have a p0236 code, and loss of power. Does anybody know where the MAP sensor is? Can it be cleaned or does it need to be replaced?

Found MAP sensor behind passenger side strut. Checked for continuity, had 22 ohms. Found TURBO BOOST PRESSURE SENSOR mounted to intercooler behind the passenger side fog light cover. Plug had water in it and connections were corroded. Replaced the part, sprayed some contact cleaner in the plug. re-seated silicone seal in plug (it was niot properly in place). Put everything back together and it is good to go. I may need a new turbo unit but I don't need it yet.
