What does P2006 mean?
The p2006 code means that the intake manifold runner control circuit has detected a stuck closed intake runner flap for bank 1. The ecu tries to control the the intake manifold runner flap position, when the malfunction is detected a check engine light is set. p2006 means the intake manifold runner control (imrc) valve on bank 1 is stuck closed. Drivers notice reduced power, hesitation on throttle lift, and a check‑engine light. Common causes: valve mechanical seizure, wiring or connector corrosion, pcm output failure, or outdated software calibration.
