Abstract

PURPOSE: To avoid occurrence of engine troubles, by properly controlling a throttle opening rate and the number of revolution of engine when there are any troubles in an output of a pressure sensor to measure a boost pressure during light load range operation of an engine.
CONSTITUTION: During light load range operation of an engine, outputs are generated from a terminal 11a of ROM11 and a terminal 24b of ROM24, and then a counter consisting of an AND gate 59, Tsec counter 60, invertor 61 and flip flop 62 initiates to count time, the flip flop 62 developing an output when such a state is held over for Tsec. In this time, where an input piping connected to a pressure sensor 16 to measure boost pressures is disconnected, an output is generated at a terminal 19a of ROM19 and a turning action from ROM20 to ROM25 is conducted, whereby a boost pressure-engine speed map operation is changed a throttle opening rate-engine speed map operation, simultaneously a warning lamp 66 being operated.
