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.
The reasons to set the diagnostic code P2005 OBD2 are the following:
The Intake Manifold Control actuator solenoid may be in poor condition.
Perhaps the intake manifold corridors are poorly adjusted.
The IMRC Sensor may be defective.
The IMRC actuator solenoid control circuit may have bad wires or connectors that cause a short.
The Manifold Absolute Pressure (MAP) Sensor may be defective.
Possible solutions of the DTC code P2005 Generic
Before establishing the problem code P2005 OBDII, you must take into account the following to solve it:
Check the TSBs available for your vehicle.
Check the system cables as well as the respective connectors. It is important to note that the IMRC actuator connectors are exposed to corrosion resulting in an open circuit. Repair as needed.
Consult the vehicle information source for IMRC actuator solenoid and Intake Manifold Control Position Sensor test recommendations. If one of these components does not meet specifications, it must be replaced.
Verify that the resistance and continuity of the actuator and sensor are as indicated by the manufacturer. Repair the circuit that does not meet these requirements.
