Code P2004 Volkswagen Description

Manufacturers can use a variable geometry intake manifold to alter airflow into the manifold under certain conditions. Under low load conditions, a long thin manifold runner is ideal for flow velocity and swirl/turbulence. Under high load demands, a short think runner is ideal. The rate of intake swirl and turbulence is critical to fuel mixture formation and agitation. A position sensor can be fixed to the control circuit to monitor the valve for both electrical and mechanical faults. An actuator test can be performed to test the circuit and live data or an oscilloscope can be used to validate the position feedback.
