    • Disclosed is a fault diagnosis apparatus for an airflow meter for determining that the airflow meter has a fault when a divergence ratio, i.e., a divergence value of an estimated intake-air quantity with respect to an actual intake-air quantity obtained by the airflow meter is greater than a fault-determination reference value determined based on a rotation speed of an internal combustion engine. As the engine speed reduces, an upper-limit diagnosis criterion increases and a lower-limit diagnosis criterion decreases, so as to narrow an area for determining that the airflow meter has a fault. Hence, the fault diagnosis for the airflow meter can be performed in the entire engine rotation speed range, i.e., in the entire operation range of the internal combustion engine, thus preventing a deterioration in the exhaust performance, which may occur owing to a failure in the airflow meter, beforehand.

    • To enable, with a simple control, a malfunction of a type wherein the output from a knock sensor becomes excessively large to be detected, a knock-sensor malfunction diagnosis device includes a control section configured to determine that knocking has occurred when the magnitude of a knocking vibration frequency component derived from an output signal from a knock sensor exceeds a first threshold value, and diagnose the knock sensor as malfunctioning when a prescribed diagnostic condition wherein knocking cannot occur is satisfied and the magnitude of the knocking vibration frequency component derived from the output signal from the knock sensor exceeds a second threshold value. The control section is further configured to determine that the diagnostic condition is satisfied for a time interval from a time when a predetermined time period has expired after fuel-cutoff has started to a time when the fuel-cutoff ends, during execution of the fuel-cutoff.
