In the pressure sensor green is signal, black is ground, brown is 5V reference. The blue I see there is probably from the ambient sensor. I don't know what all that tape is. Guessing the previous owner was working on the same problem and swapped I a non-OE sensor? No idea if this ties to your problem or not. I'd lean toward professional diagnosis.
