what does the exhaust pressure sensor do

my check engine light is on ,the code says faulty exhaust pressure sensor what does this sensor do ?????????? i have a loud whistle sound coming from my air box and was wondering if the bad sensor is related to that sound .. the whistle sound ocurs when i let off the throttle or when the auto trans shifts gears . it also make the sound about 4-5 seconds after i shut the truck ... enough time for me to get out and close the door

the sensor has nothing to do with the noise you are hearing, its just the turbo and is normal and can be especially loud if you have a 03-04
