P3406: Unleashing The Mystery Of Misfire In Cylinder 7
The P3406 code relates to the cylinder deactivation system in the engine.
The system deactivates cylinders 1 and 7 on the left bank, and cylinders 4 and 6 on the right bank, switching to a V4 mode.
Cylinder deactivation is accomplished by not allowing the intake and exhaust valves to open on the selected cylinders by using special valve lifters.
The deactivation lifters contain spring-loaded locking pins that connect the internal pin housing of the lifter to the outer housing. Switching between V8 and V4 mode is accomplished in less than 250 milliseconds, making the transitions seamless and transparent to the vehicle operator.
