A cam phaser diagnostic system is provided. The system includes: a first sample variance module that computes a first variance based on a desired cam phaser position. A second sample variance module computes a second variance based on a measured cam phaser position. An evaluation module diagnoses faulty cam phaser operation based on the first variance and the second variance.
