VGT solenoid may fail and cause over- or underboost on Ford F-350 Super Duty

The VGT solenoid can fail. The VGT solenoid receives signals from the engine control module to adjust the boost that the (variable geometry) turbo is generating. A defective solenoid can also create an overboost or underboost condition when driving.
