Code P1092 Subaru Description

The tumble generator system uses an electronically controlled butterfly valve in each intake runner port.
At cold idle, the tumble generator system will redirect the air charge through a different port. These ports have a finish characteristic that causes the air/fuel mixture to swirl and tumble greatly and create better combustion. This results in greater idle quality, cleaner emissions, and easier cold-starts.
Once the vehicle warms up, the tumble generator system will be deactivated and the intake air charge will be directed through the standard intake ports.
The Diagnostic Trouble Code (DTC) will set when the tumble generator valve is detected open when the desired position is closed.
