The PCMs programming is set to use default values if any sensor is "out of range". The impact would be that you don't get full performance of the VGT actuator and turbo performance. The idea of the variable vanes is to give you low end turbo performance by closing the vanes with low exhaust back pressure to focus the exhaust onto the turbine wheels. Think if a pistol grip garden hose nozzle that you get a stronger stream of water by squeezing the grip closed. Similar concept. Then when the engine picks up speed and subsequent exhaust back pressure, the vanes open and take full advantage of the greater volume of exhaust.

Good catch, 4x4Mark, I would agree with that. I read someone refer to the default values as "limp mode". I wouldn't call it that.

Ford is currently working on an upgrade for the EBP sensor. Apparently the current ones have issues failing or faulting out. The only fix as of now is to replace it. I found out this information on this site from a previous post.
