Code P2009 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 voltage of the intake air control valve actuator deviates from the standard range, the ECM determines that a malfunction has occurred and stores a Diagnostic Trouble Code (DTC).
