P1095 SUBARU MeaningThe 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 tumble generator sensor is responsible for measuring the position of the tumble generator butterfly valves. As the butterfly valves are opened or closed, signal voltage will vary accordingly at the position sensor.
The Diagnostic Trouble Code (DTC) will set when the Engine Control Module (ECM) detects the tumble generator valve signal is not within range.
