Abstract
A method of diagnosing a fault of a timer for monitoring an engine off time is capable of accurately determining whether a timer that monitors an engine off time between a previous start off time and a next start on time of an engine has an error by using an engine coolant temperature, an engine oil temperature, a fuel tank pressure, a fuel tank temperature, and an outside air temperature.
