The Active Fuel Management (AFM) system is also known as "cylinder deactivation." This technology allows the engine to disable half of the engine's cylinders at lower RPMs, reducing fuel use. AFM usually kicks in under light-load conditions, and it’s been shown to improve fuel economy by up to 7.5%.

If a situation arises in which the PCM cannot make the cylinder deactivation system operational (for engine bank one), or if the PCM detects that the cylinder deactivation system has become inadvertently operational, a code P3400 will be stored and a malfunction indicator lamp (MIL) may be illuminated. Cylinder Deactivation Engine:
