DTC P2004 Intake Manifold Runner Control Stuck Open (Bank 1); DTC P2006 Intake Manifold Runner Control Stuck Closed (Bank 1): Description

WARNING: This page is about a different variant/trim than selected.

The tumble control valve is built into the intake manifold. The 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 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.
