Abstract (en)
[origin: WO2017134363A1] The invention concerns a method for resetting at least two pressure sensors (Capatm, Capsural, Capadmi) positioned in an air-intake line of an internal combustion engine, the resetting compensation being calculated for at least one second sensor (Capsural, Capadmi) with respect to a first pressure sensor (Capatm) acting as a reference sensor between the respective pressure measurements of same at a so-called initial temperature of the sensors when the engine is stopped. Before applying the resetting compensation to said at least one second sensor (Capsural, Capadmi), an internal diagnostic step is carried out based on the value of the resetting compensation, consisting or determining whether the resetting compensation exceeds a maximum compensation value, in which case it is diagnosed that one of said at least two sensors is faulty. In this case, application of the resetting compensation is suspended.
