Abstract: PURPOSE: In a catalyst monitoring at rear catalyst of an exhaust system, a rear oxygen sensor are used to monitor catalyst of both bank. CONSTITUTION: An ECU monitors an engine rpm and a throttle valve opening degree to decide whether a set catalyst monitoring condition is met in a six cylinder engine(ST21, 22).
