What is turbocharger boost control solenoid replacement?
A faulty boost solenoid is replaced to restore correct turbo boost.
The boost control solenoid regulates how much the turbo is allowed to boost. When it sticks or fails electrically, the engine can lose power or over-boost and go into limp mode.
