ABSTRACT:
A pressure sensor is disposed downstream of a throttle valve in the intake tube of an internal combustion engine. When the throttle valve is closed, a throttle valve switch generates a logic signal. A monitoring of the pressure sensor is effected in that upon the simultaneous occurrence of the logic signal and a pressure signal which corresponds to an abnormal or a physically impossible state when the throttle valve is closed, an alarm is triggered.
