P2006: Intake Manifold Runner Control Stuck Closed Bank 1
A generic powertrain (engine and transmission) trouble code, same meaning on every brand.
Yes - expect the engine to feel breathless at higher revs.
Symptoms
- Loss of power at high engine speed
- Engine feels restricted when pushed
- Reduced fuel economy
Likely causes, most common first
- Runner flap stuck closed
- Carbon seizing the mechanism
- Actuator failed
- Broken linkage or vacuum diaphragm
Read P2006 yourself before paying for diagnosis
A basic Bluetooth OBD-II scanner ($20-40) plugs into the port under the dashboard and shows this code with live sensor data on your phone - useful both for confirming the fix and for talking to a shop from an informed position.
What is going on and how it gets diagnosed
P2006 is the opposite position: the flaps are stuck closed. The engine keeps its low-speed torque but cannot breathe properly when revved, so the complaint is a car that pulls away normally and then runs out of enthusiasm.
On several engines the actuator is a small electric motor with plastic gears that strip, and the flaps themselves are fine. Checking whether the actuator arm moves freely when disconnected separates a seized manifold from a failed actuator, and the price difference between those two repairs is considerable.
Repair options and cost
Typical US independent-shop ranges, parts and labor. Dealers run higher; regional labor rates vary.
