Abstract
With a precondition that a cooling water temperature sensorand an intercooler exit gas temperature sensorhave been determined normal, whether an EGR cooler efficiency calculated is within a normal range is determined. When within the normal range, whether there is divergence between a calculation value of an intake temperature to be detected by an intake manifold gas temperature sensorand an actual detection value of the sensoris determined. When not in the normal range, whether the calculation value is excessively low is determined; and, just like the above, whether there is divergence between the calculation value and the actuation detection value of the intake manifold gas temperature sensoris determined. Based on the determinations categorized, whether the EGR coolerEGR gas temperature sensorand intake manifold gas temperature sensorare normal is determined.
