The P2006 diagnostic trouble code<\/a> means the powertrain control module (PCM) has detected that the intake manifold runner control (IMRC) system is stuck in the closed position on bank 1. This prevents the engine from adjusting airflow as designed under different operating conditions.<\/p>\n\n\n\n

This code is set when the PCM commands the intake flaps to open and the feedback sensor in the actuator and the current load indicates that the butterflies are stuck in their bores or some similar issue.<\/p>\n\n\n\n

Quick Answer<\/h2>\n\n\n\n
\n
Meaning\/Definition: P2006 means the intake manifold runner control is stuck closed on bank 1.<\/li>\n\n\n\n
What it affects: Intake airflow, engine performance, and efficiency.<\/li>\n\n\n\n
How serious it is: Usually moderate; drivability may be affected, but the vehicle can often still be driven.<\/li>\n\n\n\n
Most common causes: Faulty IMRC actuator<\/a>, damaged linkage, vacuum issues, or electrical problems.<\/li>\n\n\n\n
What to do first: Check for related trouble codes and inspect the IMRC linkage and actuator.<\/li>\n\n\n\n
Can you keep using it \/ is it safe: Driving is often possible, but performance issues can worsen if ignored.<\/li>\n<\/ul>\n\n\n\n
What Does the P2006 Code Mean?<\/h2>\n\n\n\n
P2006 is defined as “Intake Manifold Runner Control Stuck Closed (Bank 1).” Bank 1 refers to the side of the engine that contains cylinder number one.<\/p>\n\n\n\n
The intake manifold runner control system adjusts airflow by opening or closing internal flaps or valves inside the intake manifold. When the PCM<\/a> commands the runners to open but detects they remain closed, it sets the P2006 code.<\/p>\n\n\n\n
