P3447: The Low Engine Exhaust Valve Control Circuit – Explained
The P3447 code refers to a fault in the cylinder deactivation system of the engine.
The system deactivates certain cylinders to improve fuel economy.
The fault is specifically related to the control circuit for the exhaust valve of cylinder 6.
The system uses special valve lifters to deactivate the cylinders.
The deactivation lifters contain spring-loaded locking pins that connect the internal pin housing of the lifter to the outer housing. The locking pins are pushed inward with engine oil pressure directed from the valve lifter oil manifold (VLOM) assembly solenoids.
The transitions between V8 and V4 mode are seamless and transparent to the vehicle operator.
