Abstract
PURPOSE: To hold the constant performance of operation even when troubled by composing the device so that the hot-wire air flow sensor can be changed to the suction air temperature correction sensor, which is an equivalent element to the former and can be changed to the fixed resistance in lieu of the suction air temperature sensor.
CONSTITUTION: Output of the hot-wire air flow sensor 12 set in the throttle chamber is fed to the multiplexer 54 through the processing circuit 59. When the air flow sensor is burned out, a signal is provided from the MPU50 to the I/O-LSI53 to apply voltage to the terminal 78. Then the relay winding 71 is energized, the respective contacts 66W70 are turned to the connection opposite to ones shown in Figure. By this, said sensor 12 is disconnected, the suction air temperature correction sensor 63 is connected so that it may be used in place of the former. At this time, the alarm lamp 61 is lighted to inform the operator that a trouble is caused.
