Abstract
In order to locate errors of the rail pressure sensor () when starting problems occur, the following method steps are proposed: determination of whether starting problems occur in the engine and if this is the case, an engine state is induced, in which the engine controller is already active but the starting phase of the engine has not yet commenced; substitution of the measured rail pressure sensor value used by the engine controller with a substitute value; start attempt of the engine and determination whether the engine has achieved an independent operation; and identification of an error function of the rail pressure sensor if the starting problems only occur when the measured rail pressure sensor value is used.
