P3474: Your Engine’s Misfire Could Be Caused By This
The P3474 code refers to the cylinder deactivation system in the engine. The system deactivates certain cylinders to improve fuel economy. The ECM determines which cylinder to deactivate based on the firing order sequence.
The deactivation is achieved by not allowing the intake and exhaust valves to open on the selected cylinders. The deactivation lifters contain spring-loaded locking pins that connect the internal pin housing of the lifter to the outer housing. The system switches between V8 and V4 mode in less than 250 milliseconds.
