Code P2004 2016 Toyota RAV4 Description

The Tumble Control Valve (TCV) is built into the intake manifold. The Intake Air Control Valve Actuator (For Tumble Control Valve) is composed of a position sensor and a DC motor. The DC motor opens and closes the tumble control valve in response to signals from the Engine Control Module (ECM). The position sensor detects the opening angle of the tumble control valve.
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.
