Zusammenfassung:	PROBLEM TO BE SOLVED: To secure detecting accuracy of a position sensor for detecting an armature position used to control a solenoid valve system (intake-exhaust valves) of an engine. SOLUTION: Before starting, initialization is performed for holding the intake valve in a closing position HIC (or a fully opening position) and the exhaust valve in a fully opening position HEO (or a closing position) to correct the relationship between an output value of the position sensor and a detecting value of the armature position on the basis of an output value VIC in the intake valve closing position of the position sensor for detecting the armature position corresponding to the intake valve and an output value VEO in the exhaust valve fully opening position of the position sensor for detecting the armature position corresponding to the exhaust valve.
