The Thermactor Idle Vacuum Valve (TIV) vents the vacuum signal to the atmosphere when preset manifold vacuum or pressure is exceeded. During periods of extended idle conditions, this valve is used to divert thermactor airflow to limit exhaust temperature, and to cut EGR in a heavy boost mode for turbocharged applications.
