P2006: Intake Manifold Runner Control Stuck Closed (Bank 1)
2 vehicles · 2 makes · $150-$800 repair
Most Reported On
P2006 is an OBD-II diagnostic trouble code meaning “Intake Manifold Runner Control Stuck Closed (Bank 1).” This code means the intake manifold runner control on Bank 1 is stuck in the closed position. Many engines use small flaps inside the intake manifold that open and close to optimize airflow for low-speed torque versus high-speed power, and an actuator moves them while a position sensor confirms their movement. When the computer commands the runners open but they stay closed (or the feedback says they're stuck), it sets this code. You may notice rough idle, hesitation, reduced power at higher RPM, or lower fuel economy. This code is most commonly reported on 2006-2015 Mercedes-Benz M-Class (ML320 CDI, ML350 CDI, ML350 BlueTEC, ML250 BlueTEC), and 2005-2014 Volkswagen Jetta (2.5 S, 2.5 SE, Base, GL, GLS, S, SE), with repair costs ranging from $150 to $800.
