2003 MAZDA PROTEGE 5 P2009 CODE

Typically, the IMRC runners are nearly closed during starting/idling conditions and opened most of the way when the throttle plate is opened. Consult your vehicle information source (All Data DIY is an excellent resource) for the particulars of the IMRC system with which the vehicle in question is outfitted. More thorough atomization helps to decrease exhaust emissions, improve fuel efficiency, and optimize engine performance.Ĭhanneling and restricting the air flow, as it is drawn into the engine, creates this swirling effect but different manufacturers use varying IMRC methods. Research has shown us that a swirling (air flow) effect helps the air/fuel mixture to be atomized more completely. The PCM controls an electronic solenoid, which regulates intake vacuum to the IMRC actuator, when a vacuum operated actuator is utilized. Some models use a vacuum diaphragm to operate the actuator. A mechanical arm or gear usually secures the IMRC actuator to the rod.

The flaps are opened with one motion, permitting all of the flaps to be rendered inoperative if one of them is stuck or binding. The thin metal runner flaps are secured (with small bolts or rivets) to a metal rod that extends the length of each cylinder head and passes through the center of each intake port. Specially shaped metal flaps, which fit tightly into the intake manifold port of each cylinder, are opened and closed by an electronic runner control actuator. It is used to manage and fine tune air as it flows into the lower intake manifold, cylinder heads, and the combustion chambers. The IMRC system is electronically controlled by the PCM.

Bank 1 points me to a malfunction that is related to the bank of the engine that contains the number one cylinder.

I know from experience that a stored code P2009, means that the powertrain control module (PCM) has detected an intake manifold air control (IMRC) actuator circuit voltage (for engine bank one) that is lower than expected. Although generic, the specific repair steps may vary depending on make/model. This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to all 1996-newer vehicles (Nissan, Honda, Infiniti, Ford, Dodge, Acura, Toyota, etc.).
