P2006 Intake Manifold Runner Control Stuck Closed (Bank 1)

EmissionsRelevant
Drive cycleNot required
Limp modePossible

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.

Likely causes

Flaps or shafts seized by deposits or wear
Runner control valve stuck from contamination
Electric actuator or its linkage failed

Symptoms

  • Malfunction indicator lamp on
  • Loss of power at higher rpm
  • Limp mode on some diesels
