System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Generic

About P2006

P2006 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P2006 is stored, the module has detected a bank-specific fault, meaning it applies only to one cylinder bank of a multi-bank engine.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P2006 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

This fault code indicates that the intake manifold runner control (IMRC) for Bank 1 is stuck in the closed position. The IMRC system adjusts airflow dynamics by changing intake runner length based on engine speed and load. When the valve remains closed when it should be open, it can restrict airflow, leading to reduced power, poor fuel economy, and increased emissions. The ECM monitors the runner position and sets this fault if it detects improper operation.
