Code P3436 Dodge Description

When all the criteria has been met,power is supplied to each Multi-Displacement System (MDS) Solenoid when engine is making a transition from 8 cylinder mode to 4 cylinder mode. By actuating the solenoid, oil pressure is raised to the pair of lifter that coincide with each particular solenoid. The oil pressure pushes in the locking pins that allows the lifter to collapse, decoupling the valves and camshafts.
