Abstract

PURPOSE:To prevent occurrence of an engine trouble, by previously storing a map, with speed and throttle opening as parameters, in addition to a map, with speed and intake negative pressure as parameters, and switching to the former at a fault of the latter. CONSTITUTION:Since the output full bit of an A/D converter 17 is input of an EX- OR gate 26, when the output full bit of the A/D converter 17 becomes ''1'' or ''0'', output of the EX-OR gate 26 becomes ''0'', that is, its inverted output becomes ''1''. Accordingly, when the inverted output of the EX-OR gate 26 is ''1'', that is, when output of an intake negative pressure PB sensor 16 is abnormal, this output is input to a CS terminal of an ROM25 through an OR gate 27, and an engine-speed Ne- throttle opening thetath map previously stored in the ROM25 is read out, then accordingly fuel injection control is performed.
