Abstract

A method of electronic engine control for a motor vehicle includes sensing an ignition voltage of a final ignition stage, effecting a performance check of the final ignition stage in response to a control signal generated in response to sensing the ignition voltage of a final ignition stage, and providing an error flag if the control signal deviates from a predetermined control signal. An apparatus for performing the foregoing method comprises an electric control circuit that includes a sensor for detecting the ignition voltage, and control means that effects a performance check in response to a sensor output signal and emits the error flag in response to an error control signal.
