Still working on it.Fan clutch switch relocated possibly shorting the 5v supply due to vibration.Did 2k miles since running ok so far but it's early to tell.Something is shorting that 5v supply line and shorting the boost pressure sensor.It is still a work in progress but it's been driving me crazy

I had the same problem....had the boost pressure sensor changed and even more fault codes showed up.
Turns out the new sensor was bad! Changed it again and all is fine. It is not really a wire problem..that is the indication that a problem has occured. .when it is really the sensor.
The mechanic told me that it could be the egr cooler is very sooted up and needs to be checked....I will do that when I am home. I will also check the sensor every couple of weeks to see if it is getting loaded with soot.
