Code details

Generic OBD-II · P2

System: Fuel / Air
Code type: Generic (SAE / ISO controlled)
Standard: SAE J2012 / ISO 15031-6

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not replace the intake manifold before confirming whether the fault is a stuck actuator, broken linkage, or a position-sensor signal.

Symptoms of P2006

Check-engine light.
Reduced top-end power or hesitation at higher RPM.
Possible rough running.

Common causes of P2006

A stuck or failed intake-runner actuator.
Broken or disconnected runner linkage.
Carbon build-up seizing the flaps.
A runner position-sensor or wiring fault.

Useful checks before replacing parts

Inspect the runner-control actuator, linkage, and flaps for binding or breakage.
Compare the actuator command with the position-sensor feedback live.
Check for carbon build-up or a seized flap shaft.
