A turbocharger boost solenoid regulates the vacuum or pressure signal that the engine management uses to set and hold the turbo's commanded boost level.
Signs the original solenoid may need replacing include boost-related trouble codes, reduced or erratic boost, or a turbo system that will not hold its commanded pressure. Because these symptoms can have other causes, diagnose the boost-control system before replacing. If a failed boost solenoid is the cause, this part replaces it. Manufacturer part number TCD103.
