ABSTRACT:
A method of examining operation of an electronic control system for an internal combustion engine having a crankshaft, the control system having a mechanism for generating pulse signals indicative of angular position of the crankshaft and a processing circuit for evaluating the indicative pulse signals so as to output pulse signals for controlling an engine operation-related factor. The mechanism generates each indicative pulse signal at a time when the crankshaft is at one of predetermined angular positions. The processing circuit outputs each control pulse signal when the crankshaft is at a desired angular position. According to the method, the indicative pulse signals are continuously counted so as to generate a succession of counted numbers, each counted number representing the number of the indicative pulse signals generated during a time from an occurrence of one the control pulse signal to an occurrence of next the control pulse signal. Then, whether or not the succession of counted numbers meets one of predetermined conditions is tested, and results of the testing are evaluated so as to examine operation of the control system.
