The DTC P2005 OBDII code setting means that the vehicle’s main computer has detected that the Intake Manifold Control (IMRC) actuator for bank 2 is stuck in the open position.
The IMRC system is controlled by the Powertrain Control Module (PCM) to manage and adjust the airflow entering the lower intake manifold, combustion chambers and cylinder heads. The corridor control solenoid is responsible for opening and closing the metal flaps in the intake port of each cylinder. These flaps are bolted to a metal bar that runs the length of each cylinder head. All the flaps can be opened at the same time with a single movement, but all of them can become inoperative if one of them gets stuck.
