What P2006 means
P2006 means the intake manifold runner or swirl flaps on bank 1 stay closed when the ECM has commanded them open. Closed flaps choke the engine at higher load, so this is the case that costs power. On GM's 2018 diesels, with swirl flaps driven by a smart actuator that reports its position, the code sets at once (Type A, one trip) when the position after the P20F8 check exceeds the limit, with coolant at 60 °C or more and the actuator powered for at least 5 s. Ford checks commanded against actual plate position after coolant exceeds 40 °F and needs four events. Volkswagen's 2024 bulletin for Golf GTI, Golf R and Arteon traced P2006 to contamination inside the runner control valve N316 that made it stick closed, fixed in production by a better vacuum hose and valve assembly.
P2006 at a glance

Symptoms of P2006
- Malfunction indicator lamp on
- Loss of power at higher rpm
- Limp mode on some diesels
Common causes of P2006
- PossibleFlaps or shafts seized by deposits or wear
- PossibleRunner control valve stuck from contamination
- PossibleElectric actuator or its linkage failed
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2006 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 0 | Area: fuel and air metering and auxiliary emission controls. |
| 06 | The exact fault in that area. |
What to do next
- Note P2006 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2006
What does P2006 mean?
P2006 means "Intake Manifold Runner Control Stuck Closed (Bank 1)". P2006 means the intake manifold runner or swirl flaps on bank 1 stay closed when the ECM has commanded them open. It is a generic code, so it means the same on every make.
Is it safe to drive with P2006?
Drive gently and only to a workshop. With P2006 the car can go into limp mode (reduced power) to protect itself.
Will P2006 fail an emissions test?
Yes, it can. P2006 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2006 to fix?
Difficulty: medium. A typical repair takes 0.5 to 4 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2006 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
