Abstract
A temperature sensor disposed in an exhaust system of an engine is inspected. Determination is made that conditions for inspecting the temperature sensor are satisfied in the current engine load range. The time for the temperature in the exhaust system to reach a value appropriate for checking the temperature sensor is determined in accordance with engine water temperature. Output of the temperature sensor is checked to determine if the temperature sensor is normal at the determined time.
