Shut-Off Valve Control
WARNING: This page is about a different variant/trim than selected.
Turbine intake shut-off valve: If vacuum is released from the turbine intake shut-off valve it will default to the closed position. The turbine intake shut-off valve position sensor will inform the ECM, which will initiate mono-turbo mode, restrict engine performance and record a DTC.
Charge air shut-off valve: If vacuum is released from the charge air shut-off valve it will default to the closed position. In the default position, the ECM initiates mono-turbo operation and restricts engine torque. A DTC will also be recorded in the ECM.
