A new method for the detection of the CPS (cam profile switching) state of spark ignition automotive engines is proposed and implemented. The method is based on the evaluation of the amplitude and the phase of the component of the intake manifold pressure signal with the period of 720 CA (crank angle) degrees. The method permits the detection of the CPS bank failure even at high rotational speeds.
