This used to be just a once in a while problem, but now every single time i start my truck when it is cold, i am getting this code, which is Turbo Boost Pressure Sensor A circuit low. And when I have this code, my boost peaks at about 10 PSI and I am not getting any fuel on the top end because my boost wont go up. Usually if i just turn the truck off, reset the code, and start again it goes away and everything is fine. This morning I could not get the code to go away, After driving the truck for about ten minutes and letting it idle for about 5, i finally got rid of the code and it drove fine. Does anyone know what might be causing this problem? It only happens on cold mornings.
