P3449: The Low-Pressure Fuel System Sensor Circuit – Explained
The P3449 code refers to the cylinder deactivation system in the engine.
The Engine Control Module (ECM) commands the system to deactivate certain cylinders to improve fuel economy. 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 transitions between V8 and V4 modes are seamless and take less than 250 milliseconds.
