HINT:
Using the Techstream to read the Data List allows the values or states of switches,
sensors, actuators and other items to be read without removing any parts. This non-intrusive
inspection can be very useful bec ...
Intake Manifold Runner Control Stuck Open (Bank 1) (P2004,P2006)
DESCRIPTION
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 sens ...
