Code P2004 2017 Toyota RAV4 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 close operation but the actual tumble control valve opening angle is 17 deg. or more for 10 seconds, Diagnostic Trouble Code (DTC) P2004 is stored.
