P0557 Suzuki Description
Brake booster pressure sensor is connected to brake booster by a hose. It detects brake booster pressure and sends the voltage signal to the Engine Control Module (ECM). The sensor uses a silicon diaphragm which is sensitive to the change in pressure. As the pressure increases, the voltage rises.
