PURPOSE:To obtain a sensor of linear and high sensibility and capable of detecting exactly an air fuel ratio in a wide range by forming porous electrodes on both surfaces of an oxygen ion conductive solid electrolyte, providing a porous electrode of measuring gas side with semicatalytic ...
[problem] can not be such that the presence or absence of failure of pressure sensor postpones as far as possible, be diagnosed with high precision. [solution] measures each fuel injection time (S104 of fuel injection valve, S106), measured fuel injection time is all, determine whether out...
