FIELD: engine devices and pumps.
SUBSTANCE: valve switches in response to a command (C) transmitted at a particular moment (t0), wherein said method comprising a stage (E2) for calculating the first form (S1) of time signal (S(t)) based on state variable change (P) of said turbine engine responding to switching of said valve, then a stage (e6) for application of valve switch signature test to the second form (S2) of said signal (S(t)) characterised in that it comprises the so-called desensitisation stage (E5), in which said second waveform (S2) of the signal is calculated based on the first waveform (S1) of the signal.
EFFECT: improved detection accuracy.
