Abstract
An electronic control system for an internal combustion engine, equipped with at least two central processing units for executing control of different operations. Counters are connected to respective ones of the central processing units for individually detecting engine speed, each of which counters counts clock pulses inputted thereto at a predetermined time interval in a predetermined operating state of the engine to thereby detect engine speed. A malfunction in each of the counters is sensed by comparing a counted value recorded by each counter and a respective stored value stored in memory. Each of the operations is enabled to be controlled based on an output from one of the counters when the other of the counters malfunctions.
