Code P2006 Lexus Description
When the tumble control valve is closed, the intake air tumble flow intensifies, and negative pressure is generated between the tumble control valve and intake valve which atomizes the fuel. Combustion is enhanced and exhaust gas emissions are reduced at low temperatures.
When the ECM has requested a tumble control valve open operation but the actual tumble control valve opening angle is less than 35 deg. for 10 seconds, DTC P2006 is stored.
