Engine Multiple Displacement System Solenoid (2009 Challenger R/T)

Understanding The Multiple Displacement System. MOPAR’s Multiple Displacement System is an emissions-related system designed to increase the fuel economy of models equipped with the 5.7L HEMI V8, such as your 2009 Dodge Challenger R/T. This system accomplishes better fuel economy by deactivating four cylinders during closed or steady throttle conditions such as idling and highway coasting. Reducing the number of cylinders being ignited means less fuel is consumed, less energy is required, and better fuel economy is experienced. Though relatively reliable, the Multiple Displacement System Solenoid is known to fail over time as most electronic components do, requiring a replacement for proper functionality. 

Replacing A Faulty MDS Solenoid. The MDS solenoid is located at each of the four cylinders routinely shut off during MDS engagement. This solenoid pumps oil into the hydraulic lifters of these cylinders, forcing them shut and locking them in place to disengage the valves from opening. However, when a solenoid fails, issues can present, such as partial cylinder deactivation, intermittent MDS activation, misfiring, poor fuel mileage, and an illuminated check engine light. If you’ve experienced any of these symptoms, it may be time to service your Challenger’s MDS with a new MDS solenoid.
