Abstract
A control apparatus for a motor vehicle which can be quickly unit tested during manufacture. Normally, the control apparatus processes signals from various operating condition sensors and applies them to determine the values of control signals to respective controlled elements, wherein there is a delay between the starting of the engine and the use of one of the sensors, namely, the exhaust gas O.sub.2 sensor in determining the value of the respective control signal. To test the apparatus, signals simulating the outputs of at least one of the sensors are set to states which are improbable in acutal operation. Upon detecting such a condition, the control apparatus removes the delay from the starting of the engine and immediately applies all output signals from the sensors to determine their respective control signals.
