Abstract
An evaporative fuel leak diagnosing apparatus for an internal combustion engine, which can detect a pressure of concern with high accuracy with a structure implemented inexpensively while ensuring high accuracy for the detection of fuel vapor. The apparatus includes a computer unit (,A) for fetching directly non-linear outputs of a pressure sensor (,A), determining a pressure detection value within a furl tank (,) on the basis of the non-linear output value of the pressure sensor (,A) and data registered previously on the basis of the non-linear output value of the pressure sensor (,A) as fetched from the computer unit for use in evaluating the actual pressure corresponding to a noted pressure sensor value.
