The turbocharger bypass valve (TBV) is a device that regulates the amount of boost pressure that is sent to the engine. When the engine is running at low speeds, the TBV is closed, which directs all of the boost pressure to the engine. As the engine speed increases, the TBV opens, which allows some of the boost pressure to escape, preventing the engine from overboosting.
The TBV is controlled by the engine control module (ECM). The ECM monitors the engine speed and boost pressure, and it opens and closes the TBV as needed to maintain the desired boost pressure.
