Abstract

A failure diagnosis controller of a pressure sensor whereby abnormalities of the pressure sensor can precisely be diagnosed, wrong abnormality diagnoses can be avoided, users' perplexity and confusion on maintenance avoided, users' distrust removed, and unnecessary maintenance eliminated. The invention provides a control means which diagnoses the pressure sensor to be in a failure mode when the intake air temperature is in a state of being measured and the integrated load of the internal combustion engine from its starting time exceeds the criterion of the integrated load.
